Going Ashore: Naval Operations in Casco Bay During World War II (Part IV)

Casco Bay Banner

By George Stewart

(This is the fourth and final installment in a series of blog posts covering the various operations conducted in Maine during WWII. Click to read Parts I, II, and III of George Stewart’s blog series about Casco Bay during WWII. To read all other post by George, go HERE.) 


This post is a continuation of the description of historical naval events that occurred in Casco Bay, Maine, during World War II. It includes a discussion of the postwar events that occurred in the bay between 1946 and 1947, plus photos of some of the historic ships that visited the bay during the war years.

The map of the area showing the basic geography and the major coastal defense facilities that appeared in Part I is repeated here for clarity. In general, the major afloat facilities including mooring, buoys, and anchorages were located on Long and Chebeague Islands with access to the open ocean by way of the gate in the anti-submarine net located in Hussey Sound, between Peaks and Long Island. Access to naval support activities in Portland was all by watercraft with trips up to approximately three to six miles. Downtown Portland also served as a “liberty port” for sailors whose ships were moored or anchored in the bay.


There are few records that cover the immediate postwar period in the bay. When the war ended, a rapid de-mobilization took place. Many ships that served during the war were decommissioned, although a significant number of these would return to service for the Korean War in 1951. Additionally, many of the ships that served in the Atlantic were transferred to the Pacific in 1945. By December 27, 1945, DESLANT consisted almost entirely of new Sumner and Gearing class destroyers, many of which were commissioned too late for significant wartime service. By this time, most shakedown and refresher training for East Coast-built ships was being conducted at Guantanamo Bay, Cuba, where it would remain up into the 1990s.

The U.S. Navy considered making further use of the bay after the war. The bay had a number of disadvantages due to its remote location, the lack of suitable docking facilities, weather, and other concerns. There were naval shore side facilities in Portland, but waterfront facilities for mooring ships were very limited due to lack of space. During the war, ships were required to anchor or moor out in the bay. This made it necessary to provide transportation to and from Portland by ferryboats, often under rather unpleasant circumstances (as shown in the following illustration below):

2Although Narragansett Bay had some of the same disadvantages, they essentially went away after the destroyer piers in Coddington Cove at Newport were completed. In retrospect, the disestablishment of the facilities in Casco Bay was probably the proper move.

In 1946, the Navy directed the Long Island Fuel Annex to be utilized for emergency refueling only. In 1962, it was placed in a caretaker status. Finally, in 1967, it was declared surplus and sold.

A total of 770 ships are on record as visiting Casco Bay between January 1941 and 1 January 1947. Destroyers and destroyer escorts comprised 480 of these ships. An additional 140 ships could have visited the bay during the aforementioned period, although it is not specifically stated in their histories. A total of 46 ships on the list were later wartime losses. Some historically significant ships that visited the bay during the war years are discussed in the following paragraphs.

BATTLESHIPS – A total of 15 battleships appear on the database. Five are still in existence as museum ships.

  • USS Texas (BB 35) – Museum ship in San Jacinto, Texas.
  • USS North Carolina (BB 55) – Museum ship in Wilmington, North Carolina.
  • USS Massachusetts (BB 59) – Museum ship in Fall River, Massachusetts.
  • USS Iowa (BB61) – Museum ship in San Pedro, California.
  • USS New Jersey (BB 62) – Museum ship at Camden, New Jersey.
USS Iowa (BB 61)

USS Iowa (BB 61)

USS Iowa (BB 61) visited Casco Bay for operational training in 1943. During that period, the ship ran aground when passing through Hussey Sound between Peaks and Long Island. Later that year, she carried President Roosevelt to and from a conference in Teheran. In 1944, the ship was transferred to the Pacific. Iowa saw active service in the Atlantic from 1984-1990. During that period, she suffered a major explosion in Turret #2 with the loss of forty-nine lives. Iowa is now serving as a museum ship in San Pedro, California. 

CARRIERS – Since the bulk of the action involving carriers occurred in the Pacific during the war, only three carriers are on record as having visited Casco Bay. An additional five escort carriers (CVE) appear in the database.

  • USS Ranger (CV 4) – First ship designed from keel up as a carrier.
  • USS Yorktown (CV 5) – Sunk in Pacific in 1942.
  • USS Wasp (CV 7) – Sunk in Pacific in 1942.
USS Ranger (CV 4)

USS Ranger (CV 4)

USS Ranger (CV 4) was the first ship designed from the keel up as a carrier. She entered service in 1934. It visited Casco Bay in 1941 as part of the Neutrality Patrol. Ranger returned in 1943 prior to supporting the invasion of North Africa. For much of the war, this was the only large carrier assigned to the Atlantic Fleet. Ranger was transferred to the Pacific in 1944.

CRUISERS – A total of twenty-two cruisers appear in the database.

  • USS Augusta (CL 31) – Carried FDR to meeting with Churchill at Placentia Bay for signing of Atlantic Charter in 1941.
  • USS Juneau (CL 52) – Sunk in the Pacific in 1942.
USS Juneau (CL 52)

USS Juneau (CL 52)

USS Juneau (CL 52) performed training exercises in Casco Bay shortly after entering service in 1942 after which it was transferred to the Pacific shortly thereafter. A torpedo off Guadalcanal sank her on 13 November 1942. This was the famed ship that the five Sullivan brothers served aboard. All were lost at sea. This incident resulted in modifications to the military “Sole Survivor” policy to prevent a reoccurrence.

DESTROYERS – A total of 263 destroyers are listed in the database. Of these, forty-seven 47 were “Four Pipers” (also referred to as “Flush Deckers”) of the Wickes and Clemson classes. These ships were carryovers from the World War I era having entered service right after the end of the war. The largest single group was the destroyers built between 1934 and 1942, with 116 ships encompassing ten different classes on the list. These ships can be recognized by their raised forecastles and in the pre-war classes, portholes in the sides. The list also includes sixty Fletcher Class ships built between 1942 and 1943 and thirty-nine Sumner and Gearing Class ships built between 1944 and 1945. These ships reverted to the “Flush Deck” configuration. Some historic ships on the list include:

  • USS Greer (DD 145) – Involved in first incident with U-Boat in 1941.
  • USS Reuben James (DD 245) – First US ship loss during war in 1941.
  • USS Hobson (DD 464) – Sunk in collision with USS Wasp in 1952.
  • USS Kearney (DD 432) – Torpedoed while on Neutrality Patrol in 1941.
  • USS Niblack (DD 424) – First action with a U-Boat in 1941.
  • USS Thompson (DD 627) – Served as the setting for The Caine Mutiny.
  • USS Charles Ausburne (DD 570) – Flagship of famous “ Little Beaver Squadron” under Capt Arleigh Burke.
  • USS Spence (DD 512) – Sunk in a typhoon in Pacific in 1943.
  • USS Gyatt (DD 712) – Converted into world’s first guided missile ship in 1956.
USS Reuben James  (DD 245)

USS Reuben James (DD 245)

USS Reuben James (DD 245) was a Clemson Class destroyer built in 1920. The ship served on Neutrality Patrol where she was sunk by a torpedo off Argentia on 23 October 1941 before the US entered the war. The last stop before she sank was Casco Bay. Rueben James was the first US ship loss of World War II.

USS Kearney(DD 432)

USS Kearney (DD 432)

USS Kearney (DD 432) was a Gleaves Class destroyer that entered service in 1940. Kearney was torpedoed while on neutrality patrol prior to outbreak of war in October 1941. She returned to duty and served as convoy escort and patrols in support of invasions of Italy and Southern France. She was sent to the Pacific in 1945.

USS Charles Ausburne (DD 570)

USS Charles Ausburne (DD 570)

USS Charles Ausburne (DD 570) was a Fletcher Class Destroyer built in Orange, Texas. She entered service in 1943 and underwent shakedown training in Casco Bay. Shortly thereafter, she was transferred to the Pacific and served as the flagship of the famous “Little Beaver” Squadron under future Chief of Naval Operations Arliegh Burke.

DESTROYER ESCORTS – Next to the destroyers, the destroyer escorts formed the second largest groups of ships to visit Casco Bay during the war. There are 223 ships on the list that visited the bay between 1944 and 1945. Those ships represented five different ship classes. USS Tills (DE 748) was mentioned in the first part of the blog series. It appears that virtually every East Coast built DE visited the bay for shakedown or ASW training at one time or another. The majority of these ships served in the Atlantic on convoy escort, ASW patrols, and as members of hunter-killer groups. A number of them were assigned to naval reserve training duties after the war. Some historically prominent ships that appear on the list include: 

  • USS Farquhar (DE 139) – Last ship to sink a U-Boat in 1945.
  • USS Stewart (DE 238) – Museum ship in San Jacinto, Texas.
  • USS Vance (DE 387) – Involved in book, The Arnheiter Affair.
  • USS Mason (DE 529) – First naval vessel with predominantly black crew.
  • USS Edward H. Allen (DE 531) – Rescued survivors from liner Andrea Doria sinking in 1956.
USS Stewart (DE 238)

USS Stewart (DE 238)

USS Stewart (DE 238) was built in Houston, Texas. The ship entered service in 1943. During the war, Stewart performed duties as a convoy escort and on ASW patrols in the Atlantic. It was transferred to the Pacific in 1945. The ship now serves as a museum ship in Galveston, Texas. In 2007, it was added to the National Register of Historic Places. She is mentioned in a separate blog on this website. Stewart is one of only two World War II-built destroyer escorts still in existence.


  • USS Denebola (AD 12) – DESLANT flagship from 1941-1944.
  • USS Yosemite (AD 19) – DESLANT flagship from 1946-1969. Served until 1994.
  • USS Vulcan (AR 5) – First USN ship with female crewmembers in 1978.
  • USS Alcor (AG 34) – DESLANT flagship in 1944-1945.
  • USS Biscayne (AGC 18) – DESLANT flagship in early 1946.
USS Yosemite (AD 19)

USS Yosemite (AD 19)

USS Yosemite (AD 19) was a Dixie Class destroyer tender built in Tampa, Florida. The ship entered service in 1944. Yosemite was initially assigned to wartime duties in the Pacific. However, it was transferred to Casco Bay in 1946 where it assumed duties as the COMDESLANT Flagship during the period where the base was closing down. In 1947, the ship was transferred to Newport, Rhode Island where she continued to serve as the DESLANT flagship until 1969. Yosemite was to remain in active service as a destroyer tender on the East Coast and in the Mediterranean until decommissioned in 1994 after fifty years of continuous service. 

MINESWEEPERS – There are thirty-six minesweepers in the database. Most were in Casco Bay for shakedown and ASW training. Unlike their post war counterparts that were (and are) of wooden hull construction, World War II minesweepers had steel hulls.

USS Jubilant (AM 255)

USS Jubilant (AM 255)

SUBMARINES – Thirty-three submarines appear on the list. The majority were home ported in New London and provided to COMDESLANT for ASW training purposes. They were generally of obsolescent types built between 1918 and 1926. Two of them were captured Italian subs used for training purposes during the latter part of the war.

S-25 in Casco Bay

S-25 in Casco Bay

The S-25 was built in 1923 and transferred to Great Britain and later to Poland. Allied Escorts later mistakenly sank the submarine off Norway in 1942.

PATROL VESSELS – Seventeen of the thirty-eight patrol vessels that appear on the list were Tacoma Class Patrol Frigates (PF). These vessels entered service between 1944 and 1945, too late to have a significant impact on the war. Many wound up being sold to foreign navies. Others were converted yachts (PY) that were used as flagships. Some historically significant vessels on the list include:

  • USS Eagle (PE 56) – Sunk by U-853 off Cape Elizabeth in 1945.
  • USS Vixen (PG 53) – Converted yacht. Served as CINCLANTFLEET flagship in 1942-1944.
  • USS Zircon (PY 16) – Converted yacht. Served as CINCLANTFLEET flagship in 1944-1945.
  • USS Mizpah (PY 29) – Converted yacht. Served as DESLANT flagship in 1945.
USS Eagle (PE 56)

USS Eagle (PE 56)

The USS Eagle (PE 56) was a World War I-built patrol vessel. It was one of sixty “Eagle Boats” built under a plan initiated by Henry Ford in a shipyard on the River Rouge near Detroit, Michigan in 1918-1919. PE 56 was one of only seven of the vessels that saw service in World War II. She was torpedoed off Cape Elizabeth, right outside Portland Harbor by U-853. However, there is still some debate as to whether or not she was torpedoed or sunk by an internal explosion. 

COAST GUARD – During World War II, the Coast Guard served as an integral part of the Navy. A total of fifty-one Coast Guard vessels appear on the list. A number of these vessels had very long service lives. Two remain on display as museum ships. Note that Coast Guard light ships were taken off station during the war and used for other purposes. The list includes seven Treasury Class cutters, several of which served into the 1980s. Some historic vessels include:

  • USCG Ingham (WPG 35) – Museum ship in Charleston, South Carolina.
  • USCG Taney (WHEC 37) – Museum ship in Baltimore, Maryland.
  • USCG Nantucket (LV 112) – Nantucket light ship – Served as an examination ship in Portland during the war.
  • USCG Portland (LV 90) – Portland light ship.
USCG Duane (WPG 33)

USCG Duane (WPG 33)

USCG Duane (WPG 33)

USCG Duane (WPG 33)




USCG Duane (WPG 33) was a Treasury Class Cutter that entered service in 1936. She remained on active service until 1985. The ship is shown above in its wartime and peacetime configurations. Duane was based in Portland from 1978-1985. 

A large number of service craft were based in Casco Bay during the war in order to provide the necessary services to ships moored out in the bay.

SS Green Island (YFB 32)

SS Green Island (YFB 32)

The vessel shown above entered service as the Casco Bay Lines steamer SS Aucocisco in 1897. The ship’s functions were to carry passengers and freight to the various islands in the bay. In 1942, the U.S. Navy took it over and re-named her USS Green Island (YFB 32). During WWII, she served as a ferryboat based in Portland to and from naval vessels moored or anchored out in the bay. Along with its sister vessel the Penobscot Bay steamer North Haven (YAG 12), Green Island served as a large “liberty boats”. A trip down the bay covered distances up to six miles from Portland and included multiple stops, often under unpleasant weather conditions. The steamer was coal fired. After the war, Green Island was returned to Casco Bay Lines where it continued to serve under its original name of Aucocisco until 1952. I rode it to and from Peaks Island a number of times in the post war era.

    Dear George:

    I was wondering if you could help me track down some historical info around Casco Bay in the days immediately after V-E day in WWII. All my Google searches have come up empty. Here’s the story that was told to me when I was very young (I’m 60 y.o. now.)
    My uncle was an enlisted man on board a Destroyer Escort (name unknown) stationed off Casco Bay. 2 days after V-E day, about 3 miles off Outer Green Island, they got a sonar contact and proceeded to put 2 depth charges into the water. After they went off, up came a German U-Boat which they captured.
    My cousin tells a similar story with just a few of the details being different. But in all my Google searches I couldn’t come up with any U-Boat capture or surrender story which matched the details of this one. It’s like we have a mystery U-Boat story here and everybody loves a mystery.
    Now if this was all I had to go on, we could write it off as some fanciful tall tale from long ago. But here’s the amazing detail which proves there is some truth to it. I’ve got evidence. This is how the story, as told to me, continued.:There were 3 Nazi flags on board that U-boat. They were the marine version, the one with the Iron Cross in the upper left hand corner. One flag (supposedly) went to an Admiral from Portland, a second to an Admiral from Boston and a third went somewhere else. To make a long story, short, one of those U-boat flags has passed into our family and we still have it. Not me, personally, I don’t have it and I haven’t seen it in years but I know it exists because when I was in 2nd grade, way back in the day, I was allowed to take it to school with me and it was my Show and Tell” exhibit that day. That’s not something you’d forget or mess up.
    So here are the questions I have. 1) If the story is true, then why isn’t there any evidence or accounts of this remarkable story? 2) Maybe the flag came from one of the 4 U-boats that surrendered at Portsmouth, NH in the days following V-E day? Perhaps. But then why do we have this amazing story about the capture and how does one explain how my uncle, an enlisted man who was only 20 y.o. at the time, get possession of the flag? Obviously, it meant something to him beyond being a very cool souvenir so why was he motivated to acquire it if the story wasn’t true? (Again, there are more details of the whole story I have left out.)
    Until I am persuaded otherwise, I’m going to go with this story as it was told to me by my uncle (unfortunately, he died a long time ago.) That means, we’ve got a mystery U-boat on our hands. But there has to be some kind of paperwork in the archives of the Navy because captured U-Boats don’t just disappear.
    If you could help me solve this mystery, I’d be much appreciative.

      I did a lot of research when I was putting together my presentation including books and web sites but I never came across this incident. An obvious place to start is It gives comprehensive lists of captured and surrendered U-Boats but does not give much detail. I expect that you may have already visited this site. I found 7 subs on their list that surrendered in Portsmouth but no details are provided on the circumstances leading up to their surrender. Subs on the list included U-2513, U-234, U-873, U-805, U-1228, U-1406, and U-505. I suspect that it was one of these but I have not been able to pin it down. I will keep looking.

    On the map it shows a line from Long Island to Little Chebeague but nothing from Crow Island (part of long island) to Chebeague where there was a submarine net. Also, I heard that there was a sub net on either Sturdivant or Basket Island. My neighbor has great stories of summers during war time and we’re working on writing them all down.

  3. Jane Blue

    I am looking for a sailor stationed in Portland Maine in 1944. His name is James Edward Staten. He was from the state of Texas and he was there in the middle of 1944. Any information would be appreciated.

  4. As a life-long resident on Casco Bay’s eastern shore (Small Point, West Point and Sebasco) and on the waters therein for 50 years. For 10 years I worked one small trawler (“Dragger”) named “Jackie B.”, which according to rumor started out as a 45 footer, but was cut in half amidships about 1940, and 10 feet was added to her waist making her a fast (16+ knots) albeit very limber, 55′ LOA by 13′ w by 7-1/2 draft vessel with a Gray Marine 671 w/ a 2 to 1 reduction.
    Being thus improved she was supposedly then used as a”sub-chaser” designed to harass but I suspect otherwise unable to attack these enemy intruders, instead to either drive them off or keep them busy until a true sub-killer could be called in to intervene.
    Is there any such truth to these tales, and if so is there any record of vessels thus commandeered?
    Would there be any photos of same???

  5. George W. Stewart

    When putting together my Casco Bay database of ship visits I found one record of a vessel that met the description. It was the converted fishing trawler Ave Maria which was assigned to the First Naval District. It performed anti submarine patrols between Boston and Portland between 1942 and 1944. The source for this information was the account of a crew member on the USS Boyd. I will look further into this and see if I can come up with any more information concerning this subject.

  6. Peter Hill

    Interesting information. Thanks. Between 1940 and 1943 I lived on Greenwood Street on Peaks Island. I was 3 when we moved there in 1940. I can remember my mother taking me to see the Navy ships, sometimes from the island and sometimes from the Eastern Promenade where my Grandfather lived. Sometimes we would see many anchored in the bay and the next day most would be gone. We would also see them when taking the boat to Portland. We also spend a lot of time on the beach between Peaks Island and Cushing Island and seem to remember a submarine net between the islands that on occasion was opened by a small boat. Do you know if that was a net that was opened to let ships in and out or am I just imagining it? Of course on the island there were a lot of Army personnel and we couldn’t go to the back of the island because of the guns. For kids it was great fun to live there at that time. Later I served as a Sonarman on destroyers out of Newport. USS Power DD-839 most of the time with a short time on USS Daly DD-519.

    • (Donald) Gerry Kennedy

      Peter, I remember you. My parents were Malcolm and Dottie Kennedy. We lived at 15 Oak Ave., about 60-80 yards away from you on Greenwood. I was born in 1936, a year before you, and was in Sub-Primary (Kindergarten) when the Japanese attacked Pearl Harbor. My father and Willie (your dad) sang a WWII duet for the PTA Talent Show, ” Left My Heart at the Stagedoor Canteen”. I have a picnic photo of you and me.

  7. George W. Stewart

    Hi Peter. You are not going to believe our connections. My grandparents, Harry & May Wallace lived on Greenwood Street in the big house on your right as you went up the hill. That is where my mother grew up and I spent my summers when I was a kid. I was born in 1935 and I remember the war years very clearly. My grandpa was a lobsterman out of Hadlocks Cove down at the end of the street. Once the net was in place he had to do all of his lobstering inside the net. Another problem was oil soaked beaches from ships being sunk offshore. I do not remember type of gate in the net. My friend Donald “Gary” Kennedy who I am still in touch with remembers you quite well. I have a copy of his auto biography in which there is a photo of you and your family having a picnic on the beach along with the Kennedys. My Uncle Harry, who drove Army boats during the war, was the next owner of your house on Greenwood Street. I grew up in Massachusetts and my parents retired to the island in 1959. I still have my connections to the island and we actually rented my grandparents’ house on Greenwood Street for a week last year. If you give me some contact information I can give you a lot more details.

    • Peter Hill

      I can’t believe it. Wow. My email is: [email protected]
      My sister who lives 10 miles away has my mothers scrap books that have clippings and a few photos from that time on the island. Happy to share. Would like to have contact with Don Kennedy if he is OK with it.

      Amazing! Thanks so much.

  8. I am searching for any information on a Navy ship stationed in Portland Maine 1943-44. The ship was the USS Capronia which may have been a converted private yacht. I am also trying to find any information about an American sailor on that ship by the name of Philip Joseph Schneider. Please e-mail any information to me at – [email protected] Thankyou Jim Graham

  9. Patricia Sanville

    Looking for a Navy ship in Portland in April or March of 1943 and may have traveled to Boston as well. Stuart C. MacDuff would have been on this Navy ship. I thought it was USS Missouri but couldn’t find him listed on it. Thanks for any help. Patty Sanville

  10. Attended Navy Signal School for 7 weeks in Casco Bay. Time was 5/44.One of the best times I had in the Navy.
    What was the name of the Island? We had to walk through the Army fort to get to the school which was located on the north end of the Island.
    Got my 3rd grade rate as soon as I returned to the Ship. Have good memories of the time there.

  11. Jim Graham

    Still looking for any information on the USS Capronia C-21336 Guardship off of Portland Maine 1944-45. Sailor Philip Joseph Schneider stationed on ship. Any information would be greatly appreciated. Jim Graham 250-768-5977, E-mail [email protected]
