On 6th June 1969 the troops of 1 Australian Task Force fought their last major urban action in Vietnam at the small rubber hamlet of Binh Ba. Up against a force of regular soldiers from the 33rd NVA Regiment and outnumbered almost three to one, the outcome was a decisive and telling victory for the Australians. The battle has been recorded in history as armour's greatest day, and yet controversy and uncertainty cloud many written accounts. This retelling, by one crewman of a Centurion tank at Binh Ba, sets out to shed new light on the story. About the Author: Dr David Hay was a national serviceman in 1968/69.
