We return to the fetid jungles of New Guinea and our Kokoda Campaign Podcast series, looking at the 53rd Battalion and it's combat performance at Isurava. This episode is the start of a series looking at Jungle Warfare Doctrine Development, with Dr Adrian Threlfall, an expert in how the Australian Army learned to learn about combat in the jungles of Malaya, Singapore, Papua, New Guinea, and many other islands to the north of Australia. Check out the  show notes for the podcast for all of the information that we cover in this episode as well as the images and other details that didn't make it into the podcast.
