HNLMS Abraham Crijnssen

HNLMS Abraham Crijnssen is a Jan van Amstel-class minesweeper of the Royal Netherlands Navy.

Built during the 1930s, she was based in the Netherlands East Indies when Japan attacked at the end of 1941. Ordered to retreat to Australia, the ship was disguised as a tropical island to avoid detection, and was the last Dutch ship to escape from the region. On arriving in Australia in 1942, she was commissioned into the Royal Australian Navy as HMAS Abraham Crijnssen and operated as an anti-submarine escort. Although returned to RNN control in 1943, the ship remained in Australian waters for most of World War II. After the war, Abraham Crijnssen operated on anti-revolution patrols in the East Indies, before returning to the Netherlands and being converted into a boom defence ship in 1956.
