>HMT Empire Windrush was a passenger motor ship that was launched in Germany in 1930 as the MV Monte Rosa. She was built as an ocean liner for the German shipping company Hamburg Süd. They used the ship to carry German emigrants to South America, and as a cruise ship. During World War II, she was taken over by the German navy and used as a troopship. During the war, she survived two Allied attempts to sink her.
>After World War II, the United Kingdom seized the ship as a prize of war and renamed her HMT Empire Windrush. She remained in British service as a troopship until 1954.

So the ship that brought Caribbean migrants over to Britain was built by Germans and was used by Germany in WW2. How ironic.
