A detailed contemporary account and analysis of the Allied seaborne assault on the Dardanelles and Gallipoli Peninsula during the First World War, reconstructing strategic objectives, operational planning, and the sequence of landings and engagements over eleven months. It combines battlefield description, assessments of military decisions, eyewitness observations of terrain and soldier life, and critical reflections on command and politics. Drawn from documents, personal notes, and interviews, it examines logistical difficulties, amphibious warfare challenges, and the human cost, while weighing whether alternative strategies might have changed the outcome.
