In late February and early March 1942, there were two aerial bombing raids. After the Fall of Singapore a few weeks prior and the shelling from a Japanese naval group on 7 March, the District Officer had hoisted the white flag. But after the Japanese naval group sailed away, the British officer raised the Union Flag once more. During the night of 10–11 March, mutinous Indian troops, abetted by Sikh policemen, killed Captain Leonard Williams and the four British NCOs in their quarters as they were sleeping. "Afterwards all Europeans on the island, including the district officer, who governed it, were lined up by the Indians and told they were going to be shot. But after a long discussion between the district officer and the leaders of the mutineers the executions were postponed and the Europeans were confined under armed guard in the district officer's house".
