Forgotten then & still forgotten now. Even though they were fighting in terrible conditions & usually badly supplied with inferior equipment they were a long way away from home & events in Europe took precedence. The surrender of Singapore is regarded as one of the greatest defeats in the history of the British Army. This is a perfect example of the mistake of underestimating the enemy. http://www.historylearningsite.co.uk/fall_of_singapore.htm
Once the Japanese expanded throughout the region after Pearl Harbour (December 1941), many in Britain felt that Singapore would become an obvious target for the Japanese. However, the British military command in Singapore was confident that the power they could call on there would make any Japanese attack useless. One story told about the attitude of the British Army in Singapore was of a young Army officer complaining that the newly completed defences in Singapore might put off the Japanese from landing there.
British troops stationed in Singapore were also told that the Japanese troops were poor fighters; alright against soldiers in China who were poor fighters themselves, but of little use against the might of the British Army.
The Japanese attitude to surrender might explain (but not condone) the terrible treatment suffered by the vast number of PoWs.
On February 8th, 1942, the Japanese attacked across the Johor Strait. Many Allied soldiers were simply too far away to influence the outcome of the battle. On February 8th, 23,000 Japanese soldiers attacked Singapore. They advanced with speed and ferocity. At the Alexandra Military Hospital, Japanese soldiers murdered the patients they found there. Percival kept many men away from the Japanese attack fearing that more Japanese would attack along the 70 mile coastline. He has been blamed for failing to back up those troops caught up directly with the fighting but it is now generally accepted that this would not have changed the final outcome but it may only have prolonged the fighting.
The Japanese took 100,000 men prisoner in Singapore. Many had just arrived and had not fired a bullet in anger. 9,000 of these men died building the Burma-Thailand railway. The people of Singapore fared worse. Many were of Chinese origin and were slaughtered by the Japanese. After the war, Japan admitted that 5000 had been murdered, but the Chinese population in Singapore put the figure at nearer 50,000. With the evidence of what the Japanese could do to a captured civilian population (as seen at Nanking), 5000 is likely to be an underestimate.
The fall of Singapore was a humiliation for the British government. The Japanese had been portrayed as useless soldiers only capable of fighting the militarily inferior Chinese. This assessment clearly rested uncomfortably with how the British Army had done in the peninsula.
The British Pacific Fleet also seems to be forgotten in much the same way. http://www.nzetc.org/tm/scholarly/tei-WH2Navy-c24.html
At the end of the war there were 142 ships in the British Pacific Fleet and 94 ships in the Fleet Train. There were some 500 first-line aircraft, 100 on ancillary services, and 1000 in reserve. The peak strength in personnel was about 125,000 officers and men. These figures were rapidly increasing, and by the end of 1945, had hostilities continued, there would have been 400 ships of all types, 900 first-line aircraft, and more than 200,000 officers and men.
