3 JULY 1940 · THE ROAD TO WAR, 1931–1941

3 Jul 1940 — Britain shells the French fleet at anchor in Algeria rather than risk it joining Hitler: 1,297 French sailors die in minutes. The ruthlessness convinces Washington that Britain means to fight on.

THE MOMENT IN CONTEXT

The Soviet Union attacked Finland in November 1939 and suffered heavy losses before finally gaining the territory it wanted, a humiliation that shaped later judgments of the Red Army. Germany then took Denmark and Norway to guard its northern flank. On 10 May 1940 German forces attacked in the west, and the plan worked by deception, since the advance in the north drew the Allied armies into Belgium while concentrated armoured divisions crossed the Ardennes and broke through the thin defences at Sedan.

From Chapter 9 — The Fall of the West of The Road to War, 1931–1941 (1940).
