How and when did the British surrendered?

British forces in Singapore have surrendered unconditionally to the Japanese seven days after enemy troops first stormed the island, which is on the 15 February 1942

A war correspondent of the Japanese News Agency in Singapore reported that fighting ceased along the entire Malayan front at 2200 local time.

The British and Japanese commanders-in-chief, Lieutenant-General Arthur Percival and Lieutenant-General Yamashita Tomoyuki met in the Ford motor plant at the foot of Bukit Timah Hill to sign the surrender documents.

The British capitulation comes one week after Japanese forces invaded Singapore and only two weeks since their onslaught on the Malay Peninsula forced the British troops' withdrawal to the island.
