These are the 4 most recent books on the Malayan Campaign and the Fall of Singapore.
Their emphasis varies. Farrell focused on the commanders and the politicians, though he left out totally the local Malayan and Singapore politicians.
Thompson’s book has lots of interviews with survivors and eye-witness accounts. Smith is an event-driven narrative.
Forgotten Armies covers a wider area. It includes Burma, India, Malaya and Singapore.
All 4 will give readers a complete picture of the Malayan and Singapore debacles.
