What is the Kokoda trail?

The Kokoda Track is a route in Papua New Guinea which leads from the village of Kokoda across the mountains into Papua towards Port Moresby. It was the route used by a small Japanese force in 1942 to attack Port Moresby. Their attack petered out as they ran out of ammunition and food,, and an Australian counter-attack in strength was mounted. It ended the southward drive by Japanese forces.
