Some of the battalion who surrendered or were captured by the Japanese on New Britain were massacred at Tol Plantation, where around 160 Australians were killed. Their bodies would later be discovered by gunners from the &lt;a href="2/14th%20Field%20Regiment%20%28Australia%29"&gt;2/14th Field Regiment&lt;/a&gt; during the Australian campaign to secure the island in 1945. Those that were not killed at Tol were interned as prisoners of war. In June 1942 they were embarked upon the "Montevideo Maru" for transport to Hainan Island. While at sea, however, on 1 July, the ship was sunk by the submarine USS "Sturgeon" off the Philippines, with 1,053 prisoners and civilian internees losing their lives. Those members of the 2/22nd that had remained at Rabaul were later transported aboard the "Natuno Maru" to Japan where they remained in captivity until they were released in September 1945, following the end of hostilities.
