To my shame I was confronted with another example of my almost complete ignorance on a slice of New Zealand history - this time with respect to the Vietnam War.
This was revealed last week when I was asked to attend the 50th commemoration of the war in Canberra on behalf of Minister of Veterans Affairs Craig Foss and the New Zealand Government.
The occasion was the anniversary of the Battle for Long Tan which was largely an Australian engagement with the North Vietnamese although some New Zealanders gave technical and artillery support. New Zealand uses this date to commemorate the war itself.
As I listened to the speeches and the recollections of the 35 veterans from New Zealand who made up our contingent, I realised how little I knew of our country's involvement. I can't name a significant battle, and my recollections revolve around black-and-white television footage from the days when I was a child at primary school. Nobody talked about it much.
To their complete insult, the returning servicemen and women were shunned by the government and the RSA - there was almost snobbery from the returned soldiers from the First and Second World Wars.
