The Guerrilla Line

Submarines of Spyron

During the period December 27, 1942 to January 25, 1945, twenty guerrilla-line submarines attached to Spyron made thirty-eight war patrols during which fifty-eight special missions were successfully accomplished in the Philippine Islands. The first Spyron mission was performed by USS Gudgeon. She sailed from Brisbane on December 27, 1942. Spyron was disbanded on January 25, 1945, after USS Nautilus offloaded the last of her forty-five tons of cargo at Baculin Bay on the western coast of Mindanao Island. Fifty percent of the special missions were performed by Nautilus and Narwhal; they also made forty percent of the patrols.
