The Contempt of citizen-soldiers for Regulars was a strong part of Canadian History too. Especially so up to the First World War but actually maintained by those in charge of our tiny regular force between wars (McNaughton basically only promoted engineers and artillerymen as those were the only troops he thought useful as Reg force).What you have to understand is that in Australia there were essentially two armies between the wars. The Regular army and the Militia army. The first were confined essentially to fortress and staff roles and the second to basically field roles. The army was further divided, we had the AIF and the militia. The AIF was formed in wartime to be able to deploy overseas on "Imperial duties" and the militia for home duties. The AIF was paid slightly better than the Militia. The regular army was looked down upon by the militia, which was made up of "citizen-soldiers" - basically part-timers and who reserved to themselves most of the command roles. In Australia we also had a long history of the "larrikin" - the roustabout civilian who ran around being trouble to his superiors and but essentially did the right thing in the end. Bennett believed he was better than most people, so good that he fled Singapore because he believed he was going to head the AIF (Australian Imperial Force). To Americans this must sound strange and even to the British it is inexplicable but to Australians it is normal. After WWII ended we established our first regular infantry force the Royal Australia Regiment but that wasn't 1945.
Even in Canada though, we would consider Bennetts actions heinous were one of ours to do the same.
