Aspects of the cruise would have been a challenge for Ralph: wading ashore after a cramped and bumpy Zodiac ride with twelve strangers; the terrifying blackfaced guy who jumped out of the jungle with a spear on Tufi; the crew talent show. But as a historian he would have loved the significant World War II sites and the buried and rusting remnants of tanks, aircraft and military vehicles in Rabaul, Alotau and Milne Bay.
The military history in Milne Bay in Alotau is dear to Australians as the site of the Battle of Milne (or “Millin” as the locals say). Yamamoto—you’ve heard of him: Japanese Admiral? Battle of Midway? Bombed Pearl Harbor? that’s the one—spent his last night in a bunker in Rabaul where hand-scawled battle maps and notes remain on the walls down in the dark. Exposed caves and tunnels reveal Japanese cargo barges, and the steel bones of sunken ships and aircraft are still half buried in the sand.
