A common view holds that 138,708 Allied personnel surrendered or were killed by fewer than 30,000 Japanese. However, the former figure includes nearly 50,000 troops captured or killed during the Battle of Malaya, and perhaps 15,000 base troops. Many of the other troops were tired and under-equipped following their retreat from the Malayan peninsula. Conversely, the latter number represents only the front-line troops available for the invasion of Singapore. British Empire battle casualties since 8 December amounted to 7,500 killed and 11,000 wounded. Japanese losses totalled around 3,500 killed and 6,100 wounded.
