Mare Island Naval Shipyard Built Submarines and Crews on “Eternal Patrol” Honored
20th Anniversary Dockside Tribute Honors 569 Crewmen of Mare Island Built Submarines Lost During World War II
VALLEJO, CA – Sunday, November 8, 2026, 1:30-3:00pm an afternoon memorial service will be held on Mare Island in Vallejo to honor the 569 crewmen of seven Mare Island built submarines lost during WWII. For the past 20 years, the Mare Island Heritage Trust has hosted a free public memorial event of history, flag-raising, bell-ringing, music and finally, a blessing of the wreath as it is laid in the Mare Island Strait/Napa River in honor of the 569 crewmen “On Eternal Patrol”.
The first Mare Island built submarine to be honored was the USS Wahoo, lost at sea on October 11, 1943. Our initial Mare Island memorial was held on October 11, 2007, simultaneously with a service for families of crew and former crew, held at Pearl Harbor, HI. Our Mare Island service honored local Bay Area resident, Eleanor Nemzera, whose brother, Lt. Richie Henderson, is one of the crew aboard the USS Wahoo, whose final resting place is a US Navy confirmed wartime grave in the La Perouse or Soya Strait in Russian waters north of Hokkaido Japan.
The 20th Lost Boats of Mare Island Memorial
Our annual dockside commemoration is now held in early November. This year, our 20th anniversary Lost Boats of Mare Island Memorial is scheduled to take place Sunday, November 8, 2026, 1:30-3:00pm. The following day, November 9, 2026 marks the 83rd anniversary of the US Navy’s official “reported missing” notice for the USS Wahoo, which was sunk with her crew of 80 men by Japanese air combat on October 11, 1943.
The Sunday afternoon event will be held at Berth 6, located at the intersection of A St. and Nimitz Ave on Mare Island in Vallejo, CA. The memorial is a dockside service of music and history ending with the laying of the memorial wreath in the Napa River/Mare island Strait. Berth 6 served as the historic WWII submarine repair and overhaul facility on Mare Island. The event is rain or shine at Berth 6.

As guests cross the “Blue Bridge” Causeway onto the former naval base, they will see the historic Navy submariners football field to the left, named for Commander Dudley W. “Mush” Morton. After the Wahoo’s loss at sea on an unknown date then, now confirmed as October 11, 1943, Mare Island Naval Shipyard honored the Commander by naming its sports field at the entrance of Mare Island, Morton Field, after the famous World War II submarine skipper.
“We hope people will join us in honoring these men who gave their lives during WWII in service of the U.S. Navy and the people of this nation. It is our privilege and responsibility to remember the lost crewmen and to honor all of those who have served our country in the submarine force. And, as importantly, we owe the men and women who built and maintained ships such as these seven submarines at Mare Island, a debt of gratitude,” said Myrna Hayes, Lost Boats of Mare Island Memorial co-organizer.
During the annual dockside service, Mr. Larry Maggini, Co-Founder of the annual lost submarine memorial, will give a presentation featuring the USS Wahoo, one of the seven vessels built, launched and overhauled and repaired at Mare Island Naval Shipyard during WWII. Mr. Maggini is an Oakville, CA resident, Lost Boats of Mare Island Memorial Co-founder and a former submarine combat systems engineer at Mare Island Naval Shipyard until the base closure in 1996.
Following the closure of the Mare Island Naval base, Mr. Maggini was employed by Weston Solutions, Inc. one of the U.S. Navy’s environmental cleanup contractors for Mare Island and a founding corporate sponsor of the USS Wahoo and Lost Boats of Mare Island Memorial events.
The dockside service will honor the 569 crewmen of the Mare Island submarines lost during WWII, including USS Wahoo and USS Tang, both lost at sea in October. The service will provide an opportunity for those in attendance to share memories and recollections.
A hand-made wreath made by volunteers from materials found on Mare Island will be placed in the Mare Island Strait to honor the 7 boats built at Mare Island and their crews, which were lost at sea during WWII. The tradition of the playing of Taps and Amazing Grace will conclude the service.
Seven Mare Island submarines on eternal patrol
The U.S. Navy submarine force went to war against the Japanese Empire in December 1941 with orders to “…conduct unrestricted submarine warfare…”. By the end of World War II in September 1945, it had sunk a significant portion of the Japanese Navy and virtually wiped out their merchant fleet, effectively strangling the island nation. According to submarine history of the Pacific Fleet, the submarine force supported all major fleet operations and made more than 1,600 war patrols. Pacific Fleet submarines, like USS Wahoo, accounted for 54 percent of all enemy shipping sunk during the war although the price paid in loss of lives and vessels was high. Fifty-two of the 325 U.S. submarines that departed on war patrols during World War II were declared, “overdue, presumed lost”. Their 3,500 crewmen representing an estimated 19 percent of the lives lost during WWII, today remain on what surviving shipmates reverently term “eternal patrol”, their final resting places in most cases, known only to God.
The Mare Island service will honor all submariners who have served in the U.S. Navy and those who have died as submariners. Seven of the twenty-three submarines built at Mare Island that took part in World War II combat operations were among the fifty-two that never came home: USS Pompano (SS-181), USS Swordfish (SS-193), USS Gudgeon (SS-211), USS Trigger (SS-237), USS Wahoo (SS238), USS Tullibee (SS-284), and USS Tang (SS-306). For more than 63 years the final resting places of the lost boats and their crews had remained unknown. For more than 60 years the search continued for the legendary World War II submarine USS Wahoo (SS 238) lost at sea on her 7th and final war patrol in the fall of 1943.
Finding the USS Wahoo
On October 31, 2006 the Commander, U.S. Navy Pacific Fleet issued a press release confirming that a wreck off Japan in Soya (La Perouse) Strait in Russian waters between Hokkaido, Japan and Sakhalin, Russia is the Wahoo, lost at sea, October 11, 1943 with her crew of eighty men. According to Navy press releases, the Navy has no plans to salvage or enter the Wahoo wreck. A long naval tradition has held that the sea is a fitting final resting place for Sailors lost at sea. The Sunken Military Craft Act protects military wrecks from unauthorized disturbance.
That announcement and planned memorial service at Pearl Harbor in October 2007, was the inspiration for Maggini and Hayes to co-found the first Mare Island memorial service to honor the Mare Island built USS Wahoo. Twenty years ago, on October 11, 2007, volunteers of the Mare Island Heritage Trust held the first of the annual flag raising and wreath-laying dockside memorial services it hosts on Mare Island in Vallejo.
The USS Wahoo was built at Mare Island and launched from Berth 19, near Building 678, at the southern end of the Naval Shipyard, February 14, 1942. She returned to Mare Island for retrofitting and left Mare Island Naval Shipyard bound for her 6th and later 7th and final patrol, on July 21, 1943.
The October 11, 2007 memorial service at Mare Island coincided with a memorial event, “On Eternal Patrol – Memorial Ceremony for the Men of USS Wahoo (SS-238)” for the families, friends and former crew members of the USS Wahoo at the USS Bowfin Submarine Museum & Park at Pearl Harbor in Hawaii. www.bowfin.org
On July 8, 2007, the U.S. Navy, while conducting routine operations off the coast of Wakkanai, Japan, held a Ceremony-at-Sea for USS Wahoo.
In July of 2006, the Russian dive team “Iskra” photographed wreckage lying in about 213 feet (65 meters) of water in the La Perouse (Soya) Strait between the Japanese island of Hokkaido and the Russian island of Sakhalin. The divers were working with The Wahoo Project Group, an international team of experts coordinated by Bryan MacKinnon, grand-nephew of Wahoo’s last Commanding Officer, Dudley W. “Mush” Morton.
The discovery of Wahoo was the culmination of more than a decade of work by an international team dedicated to finding the ill-fated submarine. In 2004, electronic surveys sponsored by a major international energy company (The Sakhalin Energy Investment Corporation) identified the likely site.
Japan Maritime Self Defense Force retired Vice Adm. Kazuo Ueda assisted the group with providing historical records from the Imperial Japanese Navy that identified the location where Wahoo was sunk.
The U.S. Navy’s Pacific Fleet Submarine Force reviewed analysis and photos provided by the Bowfin Museum and agreed the wreck is USS Wahoo. The wreck had several characteristics consistent with USS Wahoo, and the submarine was found very near those reported in Imperial Japanese Navy records. Photographs are available at www.warfish.com and www.OnEternalPatrol.com. General information about the USS Wahoo Project is available at www.usswahoo.org.
The Wahoo’s final patrol
The vessel was overhauled at Mare Island beginning in late May of 1943 and after a period of post-repair trials and training ending with a U.S. Navy award presentation to members of the crew, the Wahoo departed Mare Island for Pearl Harbor on July 21, 1943.
Wahoo was last heard from Sept. 13, 1943, as the Gato-class submarine departed the island of Midway en route to the “dangerous, yet important,” Sea of Japan. Under strict radio silence, Morton and his crew proceeded as ordered. Radio contact was expected to be regained with Midway in late October upon Wahoo’s departure from the Sea of Japan, but contact was never made. Following an aerial search of the area, Wahoo was officially reported missing 83 years ago, on Nov. 9, 1943.
At the time, the loss of Wahoo was believed due to mines or a faulty torpedo. But Japanese reports later stated that one of its planes had spotted an American submarine in the La Perouse Strait on Oct. 11, 1943. These reports indicate a multi-hour combined sea and air attack involving depth charges and aerial bombs finally sunk Wahoo.
Morton is credited with sinking 19 ships totaling nearly 55,000 tons during his four patrols in command of USS Wahoo. During Wahoo’s rare foray in the Sea of Japan, Morton reportedly sunk at least four Japanese ships. For the patrol, Morton was posthumously awarded the Navy Cross – his fourth.
Remembering the lost boats
In Larry Maggini’s photo narrative book he cites a quote by the historian Fletcher Pratt who wrote: “There is a poetry in ships’ names. It can still be heard in the quiet watches of the night…, when mist obscures the waterfront and foghorns call mournfully through the darkness. Out across the bay, blinking lights mark the channel down which Navy ships have sailed for a hundred years, and bells sound a knell for those that never came back.”
“The names of Mare Island’s lost boats are honored names—Pompano, Swordfish, Gudgeon, Trigger, Wahoo, Tullibee, and Tang. Some were old and some were new, but the sweat and the skill and the steel of Mare Island were a part of each of them to the end. The memories of them will live so long as the bells still toll. I sincerely hope the public will join us once again on Sunday, November 8 to remember the crewmen of our lost boats”, said Larry Maggini.
