First off, I know this is a forum about U-Boats, but I hope this post is allowed and someone can solve a mystery. The USS Drayton, a destroyer, reported sinking a Japanese submarine on Dec. 24, 1941, just over 3 weeks after Pearl Harbor. The captain wrote an after action report and won a Navy Cross for the action. However, I can't find a corresponding Japanese loss of a submarine in the websites I've searched covering the Imperial Japanese Navy. No Japanese sinking of a submarine appears in a list maintained by the U.S. Naval Heritage Command. If this post must be removed, I understand, but I am hoping someone will be able to find this missing Japanese sub, or direct me to a comprehensive list that will account for this action.
