How and when the British surrendered?

  The British "surrender team" (or "surrender party') in 1942 was made up of four British military officers; led by Lieutenant-General Arthur E. Percival, the rest were Brigadier K. S. Torrance, Brigadier T. K. Newbiggings, and Captain Cyril H. D. Wild. On 15 February, 1942, when the "battle for Singapore" reached its zenith, the British delegation was ordered to be at Ford Factory in Bukit Timah, to meet Lieutenant-General Tomoyuki Yamashita, head of the invading Japanese forces. He fiercely demanded the unconditional surrender of Singapore, and Percival signed the Singapore Surrender Document. 
  HistoryOn 15 February 1942, the fierce "battle for Singapore" reached its peak when Yamashita led his Japanese Imperial Army and captured Bukit Timah. He made the Ford Factory his headquarters. He had demanded specifically to see Percival.

The British delegation arrived at the Ford Factory building after 4:00 pm, led by Percival, together with Brigadier K. S. Torrance, Brigadier T. K. Newbigging carrying the Union Jack flag, and Captain Cyril Wild carrying the white surrender flag, and Lieutenant-Colonel Sugita. The meeting took place in the boardroom where Yamashita demanded from the British,an unconditional surrender of Singapore, to take effect from 8:30 pm that day. The British, with Cyril Wild as interpreter, was under heavy-pressure from Yamashita. The British broke down during negotiation. Percival on behalf of the British capitulated and signed the Singapore Surrender Document.

Winston Churchill who was convinced that Singapore was "an invincible fortress", called the fall of Singapore, "the worst disaster and largest capitulation in British history".
