World War II Headlines

Below are more images and headlines detailing important events of World War II and the German march through Europe.

Germans sink the Lancastria: The Cunard liner Lancastria, refitted for military transport, helped evacuate British troops and civilians from France. On June 17, 1940, the loaded ship was struck by German Junker 88 airplanes near the port of St. Nazaire. The bombs -- one of which is said to have gone down the ship's funnel -- were fatal. The Lancastria rolled over and sank in minutes. Many who went into the water choked on spilled fuel oil or died when the oil slick caught fire. Of the estimated 4,000 to 9,000 on board, fewer than 2,500 survived.

British remove signs as part of anti-invasion measures: In mid-1940, many in Britain believed that a German invasion was all but inevitable. Throughout the country, and especially in southern England, numerous anti-invasion measures were implemented. Road signs were removed so that parachutists would be disoriented; hundreds of concrete pillboxes were constructed in a series of east-west defensive lines; tall wooden posts were erected in open areas to disrupt parachute or glider-borne landings; hundreds of miles of barbed wire and thousands of mines were laid along the coastline; and detailed plans were made to defend every town and village. Meanwhile, the population everywhere was on the alert for spies, subversive agents, and enemy paratroopers.

Lord Beaverbrook head of British aircraft production: Lord Beaverbrook (William Maxwell Aitken) was Britain's minister of aircraft production and a member of the War Cabinet from May 1940. His sometimes ruthless but invariably focused approach, coupled with his inspired leadership, produced remarkable results during 1940. More than 7,300 aircraft were built between January and August -- just in time for the strategically vital Battle of Britain. He became minister of supply in 1941 and minister of production in 1942, while also dealing with the provision of Anglo-U.S. military aid to Russia. Soon thereafter, ill health forced the resignation of the man who Winston Churchill said was "at his best when things were at their worst."
