Bennett escaped because he believed he had information on Japanese fighting methods that could be of use in Australia. He was castigated as a coward instead. I think the charge of cowardice was very unfair to be honest. Compare that to Macs evacuation. Mac also did not want to leave his troops....at least he says that, but was ordered to do so. Bennett was not ordered to escape, but his orderes to remain were also not as specific as has been portrayed.
Bennett's escape was initially regarded as praiseworthy. Prime Minister John Curtin issued a statement that read:
"I desire to inform the nation that we are proud to pay tribute to the efficiency, gallantry and devotion of our forces throughout the struggle. We have expressed to Major General Bennett our confidence in him. His leadership and conduct were in complete conformity with his duty to the men under his command and to his country. He remained with his men until the end, completed all formalities in connection with the surrender, and then took the opportunity and risk of escaping".
In April 1942 he was promoted to lieutenant general and given command of III Corps in Perth. In 1942 this was an important post, but by 1943, as the possibility of a Japanese invasion of Australia faded, it became a backwater. Bennett was told by Blamey that he would not be given another active command, and he transferred to the Reserve of Officers in May 1944. He soon published his account of the Malayan campaign, Why Singapore Fell, which was critical of Percival and other British officers. Blamey unsuccessfully tried to prevent the book's publication.
The controversy over Bennett's actions became public in 1945, when the war ended and Percival was released from Japanese captivity. Percival, who had never got on with Bennett, accused him of relinquishing his command without permission. Blamey convened a court of enquiry under Major General V. P. H. Stanke, which found that Bennett was not justified in handing over his command, or in leaving Singapore. Veterans of the 8th Division, who were generally loyal to Bennett, protested against this finding.
In November 1945, Prime Minister Ben Chifley appointed a Royal Commission under Justice George Ligertwood. The Commission concluded that Bennett had disobeyed Percival's order to surrender.
While never questioning Bennett's personal courage, Ligertwood concluded that his action had been unjustified. Bennett's stated reason for leaving Singapore was that he had learned how to defeat the Japanese (but had been let down by British and Indian troops) and he was obliged to communicate his knowledge to military authorities.
Bennetts belief that he had something important to convey proved illusory, he proved no more proficient than other commanders in Malaya and his tactics were just as outdated. In my opinion he had escaped mostly because he etained a cherished dream to lead the Australian army, a consuming aspiration which had been sharpened by not being given an early command. His prejudice against regular officers and his ambition clouded his professional judgement at the most important point in his career. When his most cherished goals were in tatters, he convinced himself that blame for his failure lay with others. Bennet became an increaasingly bitter and resentful officer as the war progressed.
In 1948, LtCol Fry (an eminent military lawyer) published the opinion based on The Royal Commissioner. He based his report on an interpretation of international law, and did not discuss General Bennett's action from the standpoint of Australian military law, which placed him under no inflexible obligation to remain on Singapore Island.
Bennett had mad many enemiess during his career, and whilst he had an overinflated view of his own importance, there is strong evidence to support the notion that he had been stitched up in his indictment. Two men stand out as his enemies....blamey and percival.
