1917 The First World War at Sea in Photographs

America would enter the war in 1917, the unrestricted submarine warfare finally taking its toll on neutral shipping, including that of the United States. From the summer onwards, American troops would land in France in huge numbers and the blockade of Germany continued, with starvation and deprivation on a huge scale. In November, the hospital ship Britannic was lost, the largest ship of both world wars to succumb to enemy action.

Phil Carradice continues his history of the First World War at Sea using many rarely seen images.
