Singapore was far from an impregnable fortress. Fields of fire remained uncleared, landward defences were underprepared, and suitable high-explosive ammunition was scarce. One account blamed the lack of fortification on Percival's concern that digging in would hurt morale, while competing training and defence demands offer another explanation. The heavy coastal guns could turn inland, but their ammunition supply was poorly matched to that task. Japanese food and ammunition stocks were also becoming dangerously low. Their final push depended on a bluff that British commanders did not call. Holding for another couple of days might have reversed the surrender, though that remains a counterfactual judgment.

Singapore falls while Japanese supplies run low
Weak fortifications and limited ammunition combined with a battered command system, even though the Japanese attackers were themselves running short of supplies.
