In Burma... The Japanese launch an offensive aimed at destroying the British forces around Imphal and Kohima, advancing through the passes to Dimapur and cutting off the Sino-American forces in the north. Three divisions of the Japanese 15th Army (General Mutaguchi) spearhead the operation. The initial feint by the Japanese 33rd Division (General Yamagida) strikes the British 17th Indian Division (General Cowan) around Tiddim. The British forces engaged in the initial assaults are part of The 4th Corps (General Scoones). The British intend for the 17th and 20th Indian Divisions to fall back, from their forward positions, to Imphal, where they can be supplied. They underestimate the size of the Japanese forces involved in the offensive.

Over Germany... USAAF heavy bombers raid Berlin for a second time. About 10 percent of the force of 580 bombers is lost despite the escort of 800 fighters.

From Helsinki... The Finnish reply to the Soviet armistice terms with a request for further guarantees. The principal difficulty is the Soviet demand for the internment of German military personnel.

In the Solomon Islands... Japanese forces attack the American beachhead on Bougainville. The US airfields at Piva are shelled by the Japanese and some of the American bombers are withdrawn. Japanese infantry infiltrate the positions of the US 37th Division. The attacking troops are most from the Japanese 6th Division (General Hyakutake).

In the Bismark Archipelago.... On New Britain, the attacks of US 1st Marine Division makes progress as does the American advance along the coast from Cape Gloucester.
