Book excerpt: The story of USS Serpens (AK-97) is an important chapter in Coast Guard history - the most tragic loss of life in the more than 220 years of Coast Guard service to the United States. Contained within these pages is the official ship's War Diary along with some 200 personal letters sent from Serpens' crew to their friends and loved ones waiting for them to return home. On 29 January 1945, while sitting off Guadalcanal, Serpens exploded. Of the roughly 250 crew and Army stevedores on board at the time, only two Coastguardsmen survived. While this is the story of ship and crew, the final chapter still needs to be written - the awarding of the Purple Heart. It was awarded, the two who survived and several families of those killed received them, and then through misstep or miscommunication, the medal was rescinded. This is not acceptable.
