From 1914 to 1917, in severe weather conditions on the icy Baltic Sea, Russian and British submariners contested control of the sea lanes with the German Imperial Navy. Their accomplishments were largely forgotten after the war’s end. However, the Russo-British Baltic Submarine Flotilla played an important role in the war at sea in the First World War. Most significantly, in 1915 the Flotilla wreaked havoc on German naval planning and nearly cut Germany’s critical iron ore imports from Sweden. The results would lead to a strategic crisis in the German Imperial Admiralty Staff and delay Germany’s attempt to break the British blockade until 1916. Here, the significance of the Russo-British Baltic Submarine Flotilla to the broader strategy of the First World War – and its later impact on strategy in the Second World War – is re-examined.

从1914年到1917年，在冰冷的波罗的海恶劣的天气条件下，俄罗斯和英国的潜水艇手与德国帝国海军争夺了对海上航道的控制权。战争结束后，他们的成就在很大程度上被遗忘了。但是，俄英波罗的海潜艇舰队在第一次世界大战中的海上战争中发挥了重要作用。最重要的是，1915年，舰队对德国的海军计划造成了严重破坏，几乎削减了德国从瑞典进口的重要铁矿石。结果将导致德国帝国海军参谋部的战略危机，并将德国打破英国封锁的企图推迟到1916年。在这里，俄罗斯-英国波罗的海潜艇舰队对第一次世界大战的更广泛战略及其意义后来对第二次世界大战对战略的影响进行了重新审查。
