The First World War: The Submarine Strikes (Part 3)

The sinking of the RMS Lusitania on May 7, 1915, by a German U-boat off the Irish coast remains a pivotal, emotive event of the First World War that significantly influenced the United States' eventual entry into the conflict. Although a celebrated passenger liner, the ship’s transit through a declared war zone while carrying military munitions—including rifle ammunition and artillery shells—created a complex strategic dilemma. The disaster, which claimed nearly 1,200 lives, triggered a fierce propaganda war; Germany defended the act as a legitimate response to Britain’s naval blockade, while the British public framed it as an unforgivable act of barbarism. Despite persistent conspiracy theories regarding secret explosives or British orchestration, the sinking illustrates the brutal, high-stakes reality of unrestricted submarine warfare and the fragile nature of international neutrality during the Great War.
