The War Begins: Watching our own backyardIn September 1939 Britain declared war on Germany. A year later Germany formed alliances with fascist Japan and Italy. Portugal, despite its fascist dictator, remained neutral. In response to the declaration of war Australia raised an overseas army, the 2nd Australian Imperial Force (AIF) of four infantry divisions.
