The British workers were temporarily living on a ship called "Amalthea". On the night between 11 and 12 July, three young unemployed workers, including Anton Nilson, put a bomb outside "Amalthea", without considering the danger to the workers sleeping aboard. The bomb exploded, killing one and wounding 23 of the British workers, who were sleeping on the deck rather than in their cabins. The name of the Englishman killed by the explosion was Walter Close. Neither Close's family nor the injured British workers received a penny in compensation nor an apology.
