There's a St George's Day concert and God Save the King is played publicly for the first time in Stanley. The audience stands.
This is presumably with Japanese permission, as there are officials present.
Louis Hillesden Oatway dies at the French Hospital. The Hospital was locked down on May 2 and the food supply was disrupted in the wake of the arrests of that day, but as Mr. Oatway's died of cancer of the tongue this is unlikely to have been a significant contributory factor. He was born on March 11, 1893 and his home base was Plymouth in Devon. He was held in the Mee Chow Hotel before being sent to Stanley.
