Admiralty Review of German Cruiser Warfare 1914-1918 (Paperback) (ISBN-13: 9781474542609)

During World War I, the Imperial German Navy deployed surface vessels-warships, converted liners, and freighters-as commerce raiders to disrupt Allied shipping in its Handelskrieg ("Trade War"). At the outbreak of hostilities, Germany had two armoured cruisers, six light cruisers, and four gunboats stationed in colonies and neutral ports worldwide. The East Asia Squadron, under Vice Admiral Maximilian von Spee, was the centerpiece, comprising SMS Scharnhorst, Gneisenau, Emden, Leipzig, and Nürnberg. Emden achieved remarkable success raiding Indian Ocean shipping before being destroyed at the Battle of Cocos in November 1914. Spee's squadron defeated the British at Coronel in November but was annihilated at the Falkland Islands in December; only Dresden survived, eventually running aground in March 1915. Other cruisers, including Karlsruhe and Königsberg, conducted raiding operations with mixed success; Karlsruhe captured 16 ships before an internal explosion sank her in November 1914.

Fast passenger liners were converted into auxiliary cruisers, though the British blockade limited operations. Kronprinz Wilhelm was the most effective, taking thirteen prizes over eight months before internment in the United States. Prinz Eitel Friedrich captured eleven ships, while others, like Kaiser Wilhelm der Grosse and Cap Trafalgar, were quickly sunk.

After initial setbacks, Germany turned to disguised freighters as long-range raiders. SMS Möwe and Wolf conducted extended campaigns, sinking and capturing dozens of ships while evading the Royal Navy. Möwe even outfitted prizes as auxiliary raiders. Sailing raider Seeadler famously sank 13 vessels before wrecking on a reef. By 1917, surface raiding largely ceased, supplanted by unrestricted submarine warfare, which inflicted severe losses on Allied shipping but provoked neutral nations, most notably the United States, to enter the war.

Despite isolated successes, German commerce raiding failed strategically, as Allied trade adapted, and the high-risk surface raiders were progressively eliminated
