A saga of exceptional valor in World War II by Australian volunteers in the Royal Navy. Their service was diverse and dangerous, in the Battle of the Atlantic; the Arctic convoys to Murmansk in Russia; mine-clearance, covert sorties, Combined Operations in the Mediterranean and Normandy, and SE Asia. Recruited under the Dominion Yachtsmen Scheme, the Yachties war service in the Northern Hemisphere was as diverse as it was dangerous.
