The Battle of Dien Bien Phu (French: Bataille de Diên Biên Phu; Vietnamese: Chiến dịch Điện Biên Phủ) was the climactic confrontation of the First Indochina War between the French Union's French Far East Expeditionary Corps and Viet Minh communist revolutionaries. The battle occurred between March and May 1954 and culminated in a comprehensive French defeat that effectively ended the war. Military historian Martin Windrow wrote that Dien Bien Phu was "the first time that a non-European colonial independence movement had evolved through all the stages from guerrilla bands to a conventionally organized and equipped army able to defeat a modern Western occupier in pitched battle."[7]

The Battle of Singapore was fought in the South-East Asian theatre of World War II when the Empire of Japan invaded the Allied stronghold of Singapore. Singapore was the major British military base in South East Asia and nicknamed the "Gibraltar of the East". The fighting in Singapore lasted from 7 February 1942 to 15 February 1942.
It resulted in the fall of Singapore to the Japanese, and the largest surrender of British-led military personnel in history.[2] About 80,000 Indian, Australian and British troops became prisoners of war, joining 50,000 taken by the Japanese in the Malayan campaign. Britain's Prime Minister Winston Churchill called the ignominious fall of Singapore to the Japanese the "worst disaster" and "largest capitulation" in British history.
