Role in WW2
Main article: History of Samoa
Samoa declared war on Germany along with New Zealand, which administered all of Western Samoa under a League of Nations mandate. Prior to World War I, Samoa had been a German colony and was occupied by New Zealand in 1914. Under the Treaty of Versailles, Germany relinquished its claims to the islands.
Samoa sent many troops to fight with the New Zealand armed forces in the war. After the sinking of a Samoan food ship by a Japanese gunboat in 1940, the Samoan government was forced to dispatch a light-gunned ship. HMS Fa'i was in action and sank seven ships, including the attacking gunboat.
When the American armed forces entered Samoa, using it as a port, four midget submarines were spotted entering the capital Apia's port. The Samoan home guard reacted by firing a fair number of rounds, resulting in the sinking of the Hirojimi and the Shijomiki.
