On the Western Front... Operation Market Garden begins. The Allied intention is to secure key bridges over a series of rivers and canals in Holland to achieve a rapid advance onto the north German plain. On the first day, the US 101st Airborne Division secures bridges at Veghel and Zon. The US 82nd Airborne Division secures the bridge at Grave but not the one at Nijmegen. The British 1st Airborne Division, dropped near Arnhem, fails to secure the bridge there because of unexpected German resistance. Unknown to Allied planners, the 9th SS Hohenstaufen and 10th SS Frundsberg Panzer Divisions are located in Arnhem for rest and refit from combat on the Eastern Front. Meanwhile, the British 30th Corps (part of British 2nd Army) attacks northward toward Eindhoven to relieve the paratroopers. To the west, Canadian forces, also part of British 21st Army Group, launch an attack on Boulogne after a preparatory bombing by the RAF.

In the Palau Islands... US 8th Infantry Division (General Mueller) lands on Angaur. There is limited resistance by the Japanese garrison, numbering about 1600 men. On Pelelieu, American forces have consolidated their hold on the south side of the island and begin attacks on the well developed Japanese positions on Mount Umurgrobol. Despite naval bombardment supporting the advance, only limited progress is achieved by the attacks. 

In Occupied Denmark... A general strike continues in protest of recent deportations by German authorities.
