I'm currently reading an excellant book called Sinister Twilight: The Fall of Singapore and was amazed at the incompetence of the British High Command which resulted in the humilating surrender of Singapore on the 15th Febuary 1942. The Allied Army outnumbered the Japanese by 20,000 and It was the largest surrender of British led forces condemning 80,000 Allied troops to Japanese POW Camps. Many Commenwealth troops had only just recently arrived at Singapore before being forced to surrender.
Winston Churchill wrote on receiving news of the surrender "I put the telephone down. I was thankful to be alone. In all the war I never received a more direct shock."
Anymore Military Disasters ?
