USS Hornbill (AMc-13)

USS "Hornbill" (AMc-13) was a coastal minesweeper of the United States Navy, named after the hornbill.
The ship was launched as the fishing boat "J. A. Martinolich" in 1938 by the Martinolich Repair Basin, Tacoma, Washington. She was taken over by the Navy, and commissioned on 7 December 1940.
West Coast assignment.
"Hornbill" was assigned to the mine force in the 12th Naval District. She engaged in coastal sweeping of the main ship channel for magnetic and acoustic type mines. After the attack on Pearl Harbor, her service became more valuable with the Japanese threat to U.S. West Coast sea traffic. 
Collision and sinking.
On the morning of 30 June 1942 "Esther Johnson", a , steam lumber schooner on passage from Coos Bay, Oregon, collided with "Hornbill" in San Francisco Bay. Approximately thirty minutes after the collision the minesweeper sank. The crew was saved and a small amount of equipment was safely removed to the lumber schooner. She was stricken from the Naval Vessel Register on 24 July 1942.
