We lived in Malaya in the early 1950s, less than 10 years after the war ended. The local paper, The Straits Times serialised a graphic book that described what happened to men, women and children in the camps, but especially the men, the horrendous tortures. Vast numbers of the men died in the prison camps or working on the railway, they were starved of food and worked until they died. The nearest equivalent would be the Nazi Concentration camps. Those who survived to come home often died prematurely or suffered from mental illness.
What was being published would not have been put in a paper in the UK, too graphic, too unpleasant and then, would not have been published in a book either. I was 10 at the time and my mother tried to stop me reading about it all, but I did.
If you had read these accounts, you would have had precious little pity for any Japanese soldier.
Much more aware of the arrogance and superior attitudes of the colonialist 'invader' I think many of these comparisons are unsafe. Everywhere people spoke in a different tone, in a different way. Listen to the Queens voice when she became Queen and now.
In the late 1950s my father was seconded to the Malayan army along with many other army officers to help train them after independence. The army was multi-racial, Malaya is multiracial, Chinese, Indians as well as Malays and Brits and everyone was on an equal footing and socialised together.
