Actually, the Eric Bogle song relates more specifically to Anzac Day,
April 25th when the troops of Australia and New Zealand landed at
Gallipoli. These soldiers are known as ANZACS because they comprised
soldiers of both Australia and New Zealand Army Corps.

Right- when the pathetically incompetent riffraff in command are
responsible for their slaughter, then we memorialize them...Why don't
you just call it fodder day?
