the Arctic 1942: Aleutian Islands Campaign
After the attack on Pearl Harbor, the Japanese expanded rapidly across Southeast Asia and the western Pacific. Then, in a bid to draw out and destroy the outnumbered US navy, the Japanese launched twin offensives against the Aleutian Islands and Midway. In the Aleutians, Japan seized Attu and Kiska with little opposition, however their main offensive on Midway was a disaster, with the Americans sinking most of their aircraft carriers.
11 Dec 1941 Germany at war with U.S.▲
Claiming that US President Franklin Roosevelt had repeatedly violated all rules of neutrality, and noting in particular his "shoot on sight" order, Nazi Germany declared war against the United States of America. The decision to declare war was made by German leader Adolf Hitler, almost without consultation. Later that day, the United States responded by declaring war on Germany.
24–25 Dec 1941 Rallying of St. Pierre and Miquelon▲
On Christmas Eve 1941 a 230-man Free French force under Émile Muselier, and including the submarine Surcouf and three corvettes, arrived in the Vichy French-controlled islands of St. Pierre and Miquelon, partially to pre-empt a feared Canadian invasion of the archipelago. After a twenty minute stand-off, the Vichy administration agreed to a referendum the following day, which voted 98.2% in favor of Free France. The action - which had been secretly carried out despite being forbidden by the United States as contrary to the Monroe Doctrine - caused a short-lived diplomatic incident between the Americans and the Free French.

There they held out mostly alone until they could be re-supplied and equipped with anti-aircraft guns on 2 July in Operation Gearbox.
