Battle of France 1940

Paul Reynaud tells Churchill that the battle is being lost

French prime minister Paul Reynaud telephoned Winston Churchill on 15 May as German columns expanded beyond the Meuse bridgeheads and the central French front deteriorated. The government was receiving reports from a command system whose reserves were already being committed piecemeal against penetrations growing in depth and width. The northern Allied armies remained heavily engaged in Belgium. The exchange marked the moment when the operational rupture became a political crisis between allied governments. Britain now had to consider the preservation of the BEF while France sought forces capable of restoring…

Stonne changes hands repeatedly

French and German troops fought repeatedly for Stonne south of Sedan between 15 and 17 May, turning the village and surrounding ridges into one of the campaign's most violent local battles. Char B1 bis tanks, infantry and artillery demonstrated the combat power available in French formations, while German units kept the connection to the Sedan bridgehead under pressure. The fighting remained south of the principal German westward axis. German mobile formations continued toward the Oise and Somme while Stonne absorbed strong French units in a battle whose tactical intensity exceeded…

Stilwell's Party Reaches India

Stilwell and his headquarters party reached India on 15 May after the overland march from Burma. Other Allied formations were still withdrawing by different routes, and the campaign had not yet formally ended. Reaching India mattered because the Allied rear area had shifted. The old system had run from the port of Rangoon north to Lashio and China. With that route gone, India became the base from which forces would be rebuilt and new supply arrangements for China attempted. The geography of the future campaign was being established while the…

The Holocaust: Timeline and Evidence

About 437,000 Jews are deported from Hungary

German SS personnel under Adolf Eichmann worked with Hungarian officials and gendarmerie to concentrate and deport Jews from the provinces between 15 May and 9 July 1944. About 437,000 people were deported in 147 trains. About 420,000 were sent to Auschwitz-Birkenau, where the majority were murdered after arrival. Regent Miklós Horthy halted the deportations from the provinces in early July amid international pressure, military developments and growing concern over Germany's position.

Operation Deadstick

Fifty-four practice landings

The company rehearsed on canal bridges in Devon, on the Exeter ship canal and at Countess Weir, running the assault again and again until the sequence could be carried out by men who could not see. The glider pilots flew fifty-four training sorties in every weather. Howard also had them fight at night after long marches, on the reasoning that the real thing would happen to tired men in the dark. The company was widely thought to be over-trained. It was about to do the job in ten minutes.
