Lieutenant General Thomas Blamey was given command of the Second AIF on 13 October 1939 and retained it throughout the war. As such, he was answerable directly to the Minister of Defence, rather than to the Military Board. He was given a charter based on that given to Major General William Throsby Bridges in 1914. Part of his charter required the Second AIF to be kept together, but a series of political and military crises resulted in the divisions rarely fighting together, with individual divisions, brigades and even battalions deployed in different sectors or even different theatres. This resulted in conflicts with British commanders, particularly the Commander-in-Chief Middle East, General Sir Claude Auchinleck, most notably over the relief of Tobruk.
