Another carrier, HMSCourageous, was sunk three days later by U-29. By August 1942, U-boats were being fitted with radar detectors to enable them to avoid sudden ambushes by radar-equipped aircraft or ships. Nine combat launches were made, resulting in the destruction of eight Axis aircraft for the loss of one Allied pilot.[51]. In February 1942, Scharnhorst, Gneisenau and Prinz Eugen moved from Brest back to Germany in the "Channel Dash". [89][90] In Brazilian waters, eleven other Axis submarines were known to be sunk between January and September 1943the Italian Archimede and ten German boats: U-128, U-161, U-164, U-507, U-513, U-590, U-591, U-598, U-604, and U-662. WebAmerican Merchant Marine Ships Sunk or Damaged on Eastcoast and Gulf of Mexico During World War II. Over 40.000 The British, however, ignored the fact that arming merchantmen, as they did from the start of the war, removed them from the protection of the "cruiser rules",[25] and that anti-submarine trials with ASDIC had been conducted in ideal conditions.[32]. Destroyer escorts and frigates were also better designed for mid-ocean anti-submarine warfare than corvettes, which, although maneuverable and seaworthy, were too short, slow, and inadequately armed to match the DEs. Victory was achieved at a huge cost: between 1939 and 1945, 3,500 Allied merchant ships (totalling 14.5million gross tons) and 175 Allied warships were sunk and some 72,200 Allied naval and merchant seamen died. It believed that the convoy would be a waste of ships that they could not afford, considering they might be needed in battle. Early models of ASDIC/Sonar searched only ahead, astern and to the sides of the anti-submarine vessel that was using it: there was no downward-looking capability. When the convoy system was first introduced however, Britain's Royal Admiralty strongly opposed the idea. Agreement was reached in July and the exchange was completed in September 1943.[78]. ASDIC produced an accurate range and bearing to the target, but could be fooled by thermoclines, currents or eddies, and schools of fish, so it needed experienced operators to be effective. On May 7, 1915, the British ocean liner had just entered the German-declared unrestricted submarine warfare zone,which deemed any ship, even civilian and merchant ones, fair game for attack while within its borders. Britain required more than a million tons of imported material per week in order to survive and fight. They realised that the area of a convoy increased by the square of its perimeter, meaning the same number of ships, using the same number of escorts, was better protected in one convoy than in two. Several U.S. ships traveling to Britain were damaged or sunk by German mines and, in February 1915, Germany announced unrestricted warfare against all ships, In October, the slow convoy SC 7, with an escort of two sloops and two corvettes, was overwhelmed, losing 59% of its ships. The loss of a quarter of the convoy without any loss to the U-boats, despite a very strong escort (two destroyers, four corvettes, three trawlers, and a minesweeper) demonstrated the effectiveness of the German tactics against the inadequate British anti-submarine methods. General Arnold ordered his squadron commander to engage only in "offensive" search and attack missions and not in the escort of convoys. With this there was hardly any need to triangulatethe escort could just run down the precise bearing provided, estimating range from the signal strength, and use either efficient look-outs or radar for final positioning. On June 13, 1941, Commodore Leonard Murray, Royal Canadian Navy, assumed his post as Commodore Commanding Newfoundland Escort Force, under the overall authority of the Commander-in-Chief, Western Approaches, at Liverpool. Each convoy consisted of between 30 and 70 mostly unarmed merchant ships. The Condor was a converted civilian airlinera stop-gap solution for Fliegerfhrer Atlantik. As the Allied armies closed in on the U-boat bases in North Germany, over 200boats were scuttled to avoid capture; those of most value attempted to flee to bases in Norway. The campaign peaked from mid-1940 through to the end of 1943. Before the war, Norway's Merchant Navy was the fourth largest in the world and its ships were the most modern. As a result of the increased coastal convoy escort system, the U-boats' attention was shifted back to the Atlantic convoys. Following the St Nazaire Raid on 28 March 1942, Raeder decided the risk of further seaborne attack was high and relocated the western command centre for U-boats to the Chteau de Pignerolle, where a command bunker was built and from where all Enigma radio messages between German command and Atlantic based operational U-boats were transmitted/received. Ships Sunk or Damaged 1939 to 1941 Ships Captured or Detained 1939 (80 ships) Ships Sunk, Damaged or Detained 1940 (48 ships) The CAM ships and their Hurricanes thus justified the cost in fewer ship losses overall. After this initial burst of activity, the Atlantic campaign quieted down. Merchant ship losses dropped by over two-thirds in July 1941, and the losses remained low until November. All Norwegian ships decided to serve at the disposal of the Allies. Shortly afterwards U-99 was also caught and sunk, its crew captured. As an island country, the United Kingdom was highly dependent on imported goods. I was even more anxious about this battle than I had been about the glorious air fight called the 'Battle of Britain'. This declaration left any ships traveling through the region subject to sudden attacks. In May, King (by this time both Cominch and CNO) finally scraped together enough ships to institute a convoy system. Codebreaking by itself did not decrease the losses, which continued to rise ominously. U.S. [citation needed], At no time during the campaign were supply lines to Britain interrupted;[citation needed] even during the Bismarck crisis, convoys sailed as usual (although with heavier escorts). If an echo was detected, and if the operator identified it as a submarine, the escort would be pointed towards the target and would close at a moderate speed; the submarine's range and bearing would be plotted over time to determine course and speed as the attacker closed to within 1,000 yards (910m). Despite their success, U-boats were still not recognised as the foremost threat to the North Atlantic convoys. The US did not have enough ships to cover all the gaps; the U-boats continued to operate freely during the Battle of the Caribbean and throughout the Gulf of Mexico (where they effectively closed several US ports) until July, when the British-loaned escorts began arriving. The U-boats were further critically hampered after D-Day by the loss of their bases in France to the advancing Allied armies. On May 21, SSRobin Moor, an American vessel carrying no military supplies, was stopped by U-69 750 nautical miles (1,390km) west of Freetown, Sierra Leone. These aircraft were few in number, however, and directly under Luftwaffe control; in addition, the pilots had little specialised training for anti-shipping warfare, limiting their effectiveness. Web139 ships (eighty-five British and Dominion, 40 US, 10 Free French and 7 other Allied): HMCS Alberni (Canadian) HMCS Algonquin (Canadian) USS Amesbury USS Baldwin USS Barton HMS Beagle HMS Bleasdale ORP Byskawica HMS Boadicea (torpedoed and sunk 13 June) HMCS Cape Breton (Canadian) USS Carmick HMS Cattistock HMCS However, the standard approach of anti-submarine warships was immediately to "run-down" the bearing of a detected signal, hoping to spot the U-boat on the surface and make an immediate attack. Far from the only vessel victim to such attacks, the Lusitania was one of the most visible in the United States, namely because it held more than 1,900 civilians, and 128 of the nearly 1,200who died onboard were American. In April 1941 President Roosevelt extended the Pan-American Security Zone east almost as far as Iceland. [75] The next two months saw a complete reversal of fortunes. The attack on Pearl Harbor and the subsequent German declaration of war on the United States had an immediate effect on the campaign. A German U-boat torpedoed the British-owned steamship Lusitania, killing 1,195 people including 123 Americans, on May 7, 1915. The convoy was immediately intercepted by the waiting U-boat pack, resulting in a brutal battle. When one boat sighted a convoy, it would report the sighting to U-boat headquarters, shadowing and continuing to report as needed until other boats arrived, typically at night. By the time they withdrew on February 6, they had sunk 156,939tonnes of shipping without loss. If the submarine was slow to dive, the guns were used; otherwise an ASDIC (Sonar) search was started where the swirl of water of a crash-diving submarine was observed. The U-boat fleet, which was to dominate so much of the Battle of the Atlantic, was small at the beginning of the war; many of the 57available U-boats were the small and short-range Type IIs, useful primarily for minelaying and operations in British coastal waters. the Black Pit. Exercises in anti-submarine warfare had been restricted to one or two destroyers hunting a single submarine whose starting position was known, and working in daylight and calm weather. The survivors then drifted without rescue or detection for up to eighteen days. The vessels of the Norwegian Merchant Navy were placed under the control of the government-run Nortraship, with headquarters in London and New York. These aircraft first made contact with enemy submarines using air-to-surface-vessel (ASV) radar. The young U-boat commander had sunk nine Allied ships on his first sortie into U.S. waters. Convoy SC 94 marked the return of the U-boats to the convoys from Canada to Britain. U-boats disrupted coastal shipping from the Caribbean to Halifax, during the summer of 1942, and even entered into battle in the Gulf of St.Lawrence. This eventually led to the "Destroyers for Bases Agreement" (effectively a sale but portrayed as a loan for political reasons), which operated in exchange for 99-year leases on certain British bases in Newfoundland, Bermuda and the West Indies, a financially advantageous bargain for the United States but militarily beneficial for Britain, since it effectively freed up British military assets to return to Europe. One crucial development was the integration of ASDIC with a plotting table and weapons (depth charges and later Hedgehog) to make an anti-submarine warfare system. [citation needed] His ships were also busy convoying Lend-Lease material to the Soviet Union, as well as fighting the Japanese in the Pacific. There are fears more than 100 people, including children, have died after their boat sank off southern Italy. Many game graduates believe that the battle they fought on the linoleum floor is essential to their subsequent victory at sea. Not a single British warship was sunk by a U-boat in more than 20attacks. U-boats nearly always proved elusive, and the convoys, denuded of cover, were put at even greater risk. Ten ships were sunk, but another U-boat was lost. WebHe left Lorient, France on 19 Jan and nearly month later on 16 Feb 1942 sank 1 ship, the British steam tanker Oranjestad and damaged two more off Aruba. In November 1942, at the height of the Atlantic campaign, the US Navy escorted the Operation Torch invasion fleet 3,000mi (4,800km) across the Atlantic without hindrance, or even being detected. In June 1941, the US realised the tropical Atlantic had become dangerous for unescorted American as well as British ships. When news of the sinking reached the US, few shipping companies felt truly safe anywhere. [77] At the May 1943 Trident conference, Admiral King requested General Henry H. Arnold to send a squadron of ASW-configured B-24s to Newfoundland to strengthen the air escort of North Atlantic convoys. Martin Harlinghausen and his recently established commandFliegerfhrer Atlantikcontributed small numbers of aircraft to the Battle of the Atlantic from 1941 onwards. On 1 December, seven German and three Italian submarines caught HX 90, sinking 10ships and damaging three others. The British, however, developed an oscilloscope-based indicator which instantly fixed the direction and its reciprocal the moment a radio operator touched his Morse key. Although Allied warships failed to sink U-boats in large numbers, most convoys evaded attack completely. [citation needed] An estimated 1,600 merchant sailors were killed, including eight women. The first U-boats reached US waters on January 13, 1942. Many German warships were already at sea when war was declared in September 1939, including most of the available U-boats and the "pocket battleships" (Panzerschiffe) Deutschland and Admiral Graf Spee which had sortied into the Atlantic in August. Obviously this subdivision of the data ignores many other defensive measures the Allies developed during the war, so interpretation must be constrained. The Britishbegan to take U-boats more seriously after a major stealth attack decimated three of its large cruisers, the HMS Aboukir, Hogue and Cressy in September 1914. [60], In October 1941, Hitler ordered Dnitz to move U-boats into the Mediterranean to support German operations in that theatre. Meanwhile, Hitler sacked Raeder after the embarrassing Battle of the Barents Sea, in which two German heavy cruisers were beaten off by half a dozen British destroyers. The Germans had lost the technological race. Dnitz had lost his three leading aces: Kretschmer, Prien, and Schepke. At the end of the war in 1945, the Norwegian merchant fleet was estimated at 1,378ships. A new base was set up at Tobermory in the Hebrides to prepare the new escort ships and their crews for the demands of battle under the strict regime of Vice-Admiral Gilbert O. On July 3, 1942, one of these trawlers, HMS Le Tigre proved her worth by picking up 31 survivors from the American merchant Alexander Macomb. Since submarines didnt contain enough people to comprise a boarding party, and revealing their presence would forfeit any advantage, the German Navy ultimately elected for its U-boats to attack merchant and civilian ships indiscriminately. To fool Allied sonar, the Germans deployed Bold canisters (which the British called Submarine Bubble Target) to generate false echoes, as well as Sieglinde self-propelled decoys. Prior to the Lusitania'sdeparture from New York, Germany had issued warnings including several ads that ran in major newspapers alerting passengers of the potential danger: Vessels flying the flag of Great Britain or of any of her allies, are liable to destruction in the waters adjacent to the British Islesand do so at their own risk.. Because hedgehog only exploded if it hit the submarine, if the target was missed, there was no disturbed water to make tracking difficultand contact had not been lost in the first place. "[16], On 5 March 1941, First Lord of the Admiralty A. V. Alexander asked Parliament for "many more ships and great numbers of men" to fight "the Battle of the Atlantic", which he compared to the Battle of France, fought the previous summer. Operation Drumbeat had one other effect. The boats spread out into a long patrol line that bisected the path of the Allied convoy routes. 24 boats were lost in 1940. These started to be installed on anti-submarine ships from late 1942. [17] The first meeting of the Cabinet's "Battle of the Atlantic Committee" was on March 19. Often as many as 10 to 15 boats would attack in one or two waves, following convoys like SC 104 and SC 107 by day and attacking at night. As a result, the Axis needed to sink 700,000GRT per month; as the massive expansion of the US shipbuilding industry took effect this target increased still further. Although the number of ships the raiders sank was relatively small compared with the losses to U-boats, mines, and aircraft, their raids severely disrupted the Allied convoy system, reduced British imports, and strained the Home Fleet. In the Battle of the Denmark Strait, the battlecruiser HMSHood was blown up and sunk, but Bismarck was damaged and had to run to France. WebIn less than seven months, U-boat attacks would destroy 22 percent of the tanker fleet and sink 233 ships in the Atlantic Ocean and the Gulf of Mexico. WebIn the course of events in the Atlantic alone, German U-boats sank almost 5,000 ships with nearly 13 million gross register tonnage, losing 178 boats and about 5,000 men in The harsh winter of 193940, which froze over many of the Baltic ports, seriously hampered the German offensive by trapping several new U-boats in the ice. The British also made extensive use of shore HF/DF stations, to keep convoys updated with positions of U-boats. 3, allowing the Germans to estimate where and when convoys could be expected. No troop transports were lost, but merchant ships sailing in US waters were left exposed and suffered accordingly. This was thought to be safe as the radio messages were encrypted using the Enigma cipher machine, which the Germans considered unbreakable. These hunting groups had no success until Admiral Graf Spee was caught off the mouth of the River Plate between Argentina and Uruguay by an inferior British force. Any merchant ship that was stopped and discovered to be holding contraband cargo could be captured, boarded and escorted to a designated harbor. Since the wolf pack relied on U-boats reporting convoy positions by radio, there was a steady stream of messages to intercept. A large convoy was as difficult to locate as a small one. In August, 1942, the UK Admiralty was informed. Damaged ships might survive but could be out of commission for long periods. According to German sources, only six aircraft were shot down by U-flaks in six missions (three by U-441, one each by U-256, U-621 and U-953). Above 15 knots (28km/h) or so, the noise of the ship going through the water drowned out the echoes. [83] After a series of attacks on merchant vessels off the Brazilian coast by U-507,[83] Brazil officially entered the war on 22 August 1942, offering an important addition to the Allied strategic position in the South Atlantic. More U-boats were sunk, but the number operational had more than tripled. The first batch of Type IXs was followed by more Type IXs and Type VIIs supported by Type XIV "Milk Cow"[63] tankers which provided refuelling at sea. By 1945 the USN was able to wipe out a wolf-pack suspected of carrying V-weapons in the mid-Atlantic, with little difficulty. Designs were finalised in January 1943 but mass-production of the new types did not start until 1944. More than 2,400 British ships were sunk. After the country resumed unrestricted submarine warfare once more, Wilson cut diplomatic ties. This gave them much greater tactical flexibility, allowing them to detach ships to hunt submarines spotted by reconnaissance or picked up by HF/DF. WebThe Battle of the Atlantic, New York: Dial Press,1977. Later that May afternoon, the German submarine U20sent a single torpedo through the side of the Lusitania, triggering an explosion inside the ship, and sinking it within 18 minutes. The captured material allowed all U-boat traffic to be read for several weeks, until the keys ran out; the familiarity codebreakers gained with the usual content of messages helped in breaking new keys. When it came to capturing merchant ships during wartime, ships that traveled on the surface were required to adhere to specific rules set by international treaties. The first such receiver, named Metox after its French manufacturer, was capable of picking up the metric radar bands used by the early radars. When he spotted the Gulfamerica five miles off Jacksonville Beach on April 11, 1942, the tanker loaded with 101,500 barrels of furnace oil was not running a zigzag course, a standard for ships in a combat zone. By May, wolf packs no longer had the advantage and that month became known as Black May in the U-boat Arm (U-Bootwaffe). ASDIC was effective only at low speeds. This quickly led to the loss of seven U-boats. The ordinary sailors, however, had no uniform and when on leave in Britain they sometimes suffered taunts and abuse from civilians who mistakenly thought the crewmen were shirking their patriotic duty to enlist in the armed forces. Although the narrow fjords gave U-boats little room for manoeuvre, the concentration of British warships, troopships and supply ships provided countless opportunities for the U-boats to attack. Instead, German naval strategy relied on commerce raiding using capital ships, armed merchant cruisers, submarines and aircraft. [26] Convoys allowed the Royal Navy to concentrate its escorts near the one place the U-boats were guaranteed to be found, the convoys. Overall, more than 99% of all ships sailing to and from the British Isles during World War II did so successfully. Admiral Scheer quickly sank five ships and damaged several others as the convoy scattered. Many of these ships became part of the huge expansion of the Royal Canadian Navy, which grew from a handful of destroyers at the outbreak of war to take an increasing share of convoy escort duty. Advertising Notice Nevertheless, with intelligence coming from resistance personnel in the ports themselves, the last few miles to and from port proved hazardous to U-boats. As a result, the Royal Navy entered the Second World War in 1939 without enough long-range escorts to protect ocean-going shipping, and there were no officers[citation needed] with experience of long-range anti-submarine warfare. In early 1941, the problems were determined to be due to differences in the earth's magnetic fields at high latitudes and a slow leakage of high-pressure air from the submarine into the torpedo's depth regulation gear. The first of these destroyers were only taken over by their British and Canadian crews in September, and all needed to be rearmed and fitted with ASDIC. A month later, SL 67 was saved by the presence of HMSMalaya. However, many passengers adopted Turners skeptical attitude given the over 200 transatlantic trips the ship had previously made and its reputation as a speedy Greyhound of the sea. Following the deaths of at least 64 migrants in a shipwreck off Italy s southern coast on Sunday, police arrested three persons on suspicion of people Time and again, U-boat captains tracked British targets and fired, only to watch the ships sail on unharmed as the torpedoes exploded prematurely (due to the influence pistol), or hit and fail to explode (because of a faulty contact pistol), or ran beneath the target without exploding (due to the influence feature or depth control not working correctly). [98], Dan van der Vat suggests that, unlike the US, or Canada and Britain's other dominions, which were protected by oceanic distances, Britain was at the end of the transatlantic supply route closest to German bases; for Britain it was a lifeline. The British officers wore uniforms very similar to those of the Royal Navy. Due to ongoing friction between the Luftwaffe and Kriegsmarine, the primary source of convoy sightings was the U-boats themselves. This failure resulted in the build-up of troops and supplies needed for the D-Day landings. It worked simply with a crossed pair of conventional and fixed directional aerials, the oscilloscope display showing the relative received strength from each aerial as an elongated ellipse showing the line relative to the ship. The supply situation in Britain was such that there was talk of being unable to continue the war, with supplies of fuel being particularly low. Germany made several attempts to upgrade the U-boat force, while awaiting the next generation of U-boats, the Walter and Elektroboot types. The intention was to pass over the submarine, rolling depth charges from chutes at the stern at even intervals, while throwers fired further charges some 40yd (37m) to either side. A three-barrelled mortar, it projected 100lb (45kg) charges ahead or abeam; the charges' firing pistols were automatically set just prior to launch. On the anniversary of the sinking of the Lusitania, a look at how unrestricted submarine warfare changed the rules of war. In 1941, American intelligence informed Rear Admiral John Henry Godfrey that the UK naval codes could be broken. Dnitz calculated 300 of the latest Atlantic Boats (the Type VII), would create enough havoc among Allied shipping that Britain would be knocked out of the war. To effectively disable a submarine, a depth charge had to explode within about 20ft (6.1m). In addition, the Kriegsmarine used much more secure operating procedures than the Heer (Army) or Luftwaffe (Air Force). Squadron Leader J. Thompson sighted the U-boat on the surface, immediately dived at his target, and released four depth charges as the submarine crash dived. [93] From then on, the battle in the region was lost by Germany, even though most of the remaining submarines in the region received an official order of withdrawal only in August of the following year, and with (Baron Jedburgh) the last Allied merchant ship sunk by a U-boat (U-532) there, on 10 March 1945.[94]. [54] The rotors were changed every other day using a system of key sheets and the message settings were different for every message and determined from "bigram tables" that were issued to operators. As of April 1915, German forces had sunk 39 ships and lost only three U-boats in the process. Following some early experience in support of the war at sea during Operation Weserbung, the Luftwaffe began to take a toll of merchant ships. While escorts chased individual submarines, the rest of the "pack" would be able to attack the merchant ships with impunity. Norwegian Nazi puppet leader Vidkun Quisling ordered all Norwegian ships to sail to German, Italian or neutral ports. Though these were British inventions, the critical technologies were provided freely to the US, which then renamed and manufactured them. The. [28] Similar problems plagued the US Navy's Mark 14 torpedo, but it ignored the reports of German problems.[29]. In July 1942, Hans-Rudolf Rsing was appointed as FdU West (Fhrer der Unterseeboote West). The Leigh Light enabled attacks on U-boats recharging their batteries on the surface at night. Some British naval officials, particularly the First Lord of the Admiralty, Winston Churchill, sought a more 'offensive' strategy. The sinking of Allied merchant ships increased dramatically. WebHow many American ships did U-boats sink? WebSix days later, 128 Americans lost their lives when the British passenger liner Lusitania was sunk by German U-Boats. On this Wikipedia the language links are at the top of the page across from the article title. An extraordinary incident occurred when a Coastal Command Hudson of 209 Squadron captured U-570 on 27 August 1941 about 80 miles (130km) south of Iceland. The German occupation of Norway in April 1940, the rapid conquest of the Low Countries and France in May and June, and the Italian entry into the war on the Axis side in June transformed the war at sea in general and the Atlantic campaign in particular in three main ways: The completion of Hitler's campaign in Western Europe meant U-boats withdrawn from the Atlantic for the Norwegian campaign now returned to the war on trade. To this end, the Admiralty asked the Royal Canadian Navy on May 23, to assume the responsibility for protecting convoys in the western zone and to establish the base for its escort force at St. John's, Newfoundland. So there was a time lag between the last fix obtained on the submarine and the warship reaching a point above that position. The outcome of the battle was a strategic victory for the Alliesthe German blockade failedbut at great cost: 3,500merchant ships and 175warships were sunk in the Atlantic for the loss of 783U-boats (the majority of them Type VII submarines) and 47 German surface warships, including 4 battleships (Bismarck, Scharnhorst, Gneisenau, and Tirpitz), 9 cruisers, 7 raiders, and 27 destroyers. The disastrous convoy battles of October 1940 forced a change in British tactics. By 1945, just one TypeXXI boat and five TypeXXIII boats were operational. Terms of Use The hunting group strategy proved a disaster within days. After Convoy ON 154, winter weather provided a brief respite from the fighting in January before convoys SC 118 and ON 166 in February 1943, but in the spring, convoy battles started up again with the same ferocity. [56] In early 1941, the Royal Navy made a concerted effort to assist the codebreakers, and on May 9 crew members of the destroyer Bulldog boarded U-110 and recovered her cryptologic material, including bigram tables and current Enigma keys. In particular, this was because most of the ships sunk by U-boats were not in convoys, but sailing alone, or having become separated from convoys. The Lusitania attack put increased public pressure on the Wilson administration to reconsider United States involvement in World War I, leading up to an official declaration of war in 1917. This made it far more difficult to evade contact, and the wolf packs ravaged many convoys. The advent of long-range search aircraft, notably the unglamorous but versatile PBY Catalina, largely neutralised surface raiders. By spring 1943, the British had developed an effective sea-scanning radar small enough to be carried in patrol aircraft armed with airborne depth charges. The situation was so bad that the British considered abandoning convoys entirely. The British codebreakers needed to know the wiring of the special naval Enigma rotors, and the destruction of U-33 by HMSGleaner (J83) in February 1940 provided this information. In 1943, the United States launched over 11million tons of merchant shipping; that number declined in the later war years, as priorities moved elsewhere. For the first half of 1940, there were no German surface raiders in the Atlantic because the German Fleet had been concentrated for the invasion of Norway. It is maintained by G. H. Persall[97] that "the Germans were close" to economically starving England, but they "failed to capitalize" on their early war successes.
