Saving Singapore's papers would not conceal Malaya's defenses

Preventing the capture of British planning papers would help only marginally because Japanese intelligence had many other ways to observe British forces and empty airfields.

Question

What if the War Office papers in Singapore had been saved from Japanese capture?

Short answer

Britain would gain a small advantage, but Japan could still infer most deployments and weaknesses from other intelligence and visible preparations.

Notes

Destroying or evacuating the War Office papers would improve the British position slightly. Japan already possessed extensive information about deployments in Malaya. British Army activity was visible, and the Royal Air Force was constructing bases without enough aircraft to fill them. Document security could not conceal weaknesses advertised by the wider operational posture.
