This year 70 years ago on Christmas Day 1941, after a successful operation off the northern coast of Borneo the night before, HMS K-XVI was torpedoed by Japanese Submarine I-66. All crew members were killed. Contemporaries of the commander of K-XVI, and later commentators, criticized his actions after his successful attack on that Christmas Eve. They suggest that his actions may have led to the sinking of K-XVI. In my opinion a totally unjustified criticism.
The following article is a (very) short version of a comprehensive analysis that I made some years ago regarding the sinking of HMS K-XVI.
