The adversaries of U-boats were mostly small anti-submarine ships like destroyers, destroyer escorts, frigates and corvettes, but on a few occasions U-boats could sink capital ships in the Atlantic: the battleship Royal Oak was sunk in harbour, the aircraft carrier Courageous was sunk while on anti-submarine patrol, the paki girl escort london carriers Audacity, Avenger and Block Island were sunk while escorting convoys, and the light cruiser Dunedin was sunk searching for German raiders. Of the much awaited elektroboote, only five Type XXIII coastal elektroboote made seven patrols in 1945 which sank five small freighters. Another nineteen type IX U-boats sailed for the Americas; these U-boats sank three small warships and three merchants for the loss of nine of their own. They sank six warships and nine merchants ships for the loss of seven U-boats. Six were in Japan at the time of the German surrender and were captured by the Japanese.

In order to keep up the offensive pending the arrival of the elektroboote, 68 patrols were organised from Norway towards British waters between July and December 1944. Only schnorkel Type VII U-boats could be used as Allied air superiority excluded continuous cruising on surface.

In 1945 Dönitz continued with the same approach: type VII schnorkel U-boats mounted 113 patrols to British waters from Norway and Germany. The last actions in American waters took place on 5-6 May 1945, which saw the sinking of the steamer Black Point and the destruction of U-853 and U-881 in separate incidents. Between 1939 and 1945, 72,200 Allied naval and merchant seamen died. Information obtained by British agents regarding German shipping movements led Canada to conscript all its merchant vessels two weeks before declaring war, with the Royal Canadian Navy taking control of all shipping on 26 August 1939. At the outbreak of the war, Canada possessed 38 ocean-going merchant vessels. The British officers wore uniforms very similar to those of the Royal Navy. To counter this, the crewmen were issued with an 'MN' lapel badge to indicate they were serving in the Merchant Navy. During the Second World War nearly one third of the world's merchant shipping was British. The British merchant fleet was made up of vessels from the many and varied private shipping lines, examples being the tankers of the British Tanker Company and the freighters of Ellerman and Silver Lines.

The British government, via the Ministry of War Transport (MoWT), also had new ships built during the course of the war, these being known as Empire ships. Normandy landings. During the course of World War II, this class participated in the sinking of at least 34 German submarines and a number of other hostile craft with 15 of the 78 Captain-class frigates being either sunk or written off as a constructive total loss. The Nazi Germa­n armies that moved ­relentlessly toward Stalingrad in summer 1942 dur­ing World War II were confronted with a bleak terrain. The other three bases in Lorient, St-Nazaire and La Pallice were evacuated but remained in German hands until the end of the war. Sixty-five U-boats were lost by the end of the war.

Burr believed that women were the intellectual equals of men - his own wife was a voracious reader of Greek classics and Edward Gibbons' multi-volume "History of the Decline and Fall of the Roman Empire," according to Isenberg's book - and he and his wife made sure that Theodosia got an education as fine as any upper-class male child. The ships were crewed by sailors from all over the British Empire, including 25% from India and China, and 5% from the West Indies, Middle East and Africa. The Germans lost about 30,000 U-boat sailors killed, three-quarters of the 40,000-man U-boat fleet. The defeat of the U-boat was a necessary precursor for accumulation of Allied troops and supplies to ensure Germany's defeat.
