Rosneath naval base was a naval base, constructed on the Rosneath peninsula, Argyll and Bute, Scotland.^[1] close to the village of Rosneath.^[2] The construction of the base started in July 1941, in response to American expectations that they would be shortly entering World War II.^[3] In June 1945, the base was decommissioned, then fell into disuse and was finally closed in 1948.^[3]

Rosneath castle

Rosneath Castle was situated at the head of the bay,^[4] and used as transient officers accommodation and as an officers mess. The castle had been rebuilt by George Douglas Campbell, 8th Duke of Argyll in 1860 for Princess Louise, Duchess of Argyll.^[1] The castle and estate was sold in early 1940, ending 500 years of Clan Campbell ownership of Rosneath and the surrounding area.^[3]

Construction begins

Rosneath Bay was chosen as the area of the base as its location in Firth of Clyde provided deep water channels that were considered excellent for ship operations and sufficient land at Rosneath estate was provided that was both flat for tanks, combined with a hilly and wooded area that provided excellent protective coverage for buildings.^[1] The initial construction of the base was started when funds were provided as part of the Lend-Lease agreement.^[1] Contract workers and material started to arrive in June 1941.^[1] In July 1941,the American Civil Engineer Corps and Seabees along with civilian personnel arrived to find the Royal Engineers, 996 Dock Operating Company^[3] constructing a shallow water jetty for barges.^[1] In August 1941, 150 Irish workmen were contracted and began work immediately.^[1] Although shiploads of construction machinery arrived from the US,^[3] work was delayed due to the lack of a rock crusher, which meant the local quarry, which was 25 miles away, needed to be used for the delivery of aggregate.^[1] By December 1941, work was advanced, on the barracks, hospital, reservoirs, roads and the water filter and purification plant.^[1]

In the same month the United States joined the war and the scope of work was reduced by one-third. Instead of the three specialities of submarine facilities, destroyer facilities and repair shops being offered at the base, it was decided to remove the destroyer facilities.^[1] Any work for the destroyer facilities was subsequently cancelled and the tank farm, hospital and support functions were all reduced in size, to take cognizance of the smaller size of base.

Operation Torch

On the 24 August 1942, the base was again commissioned by the United States Navy to train amphibious craft sailors as part of combined operations preparations for the Allied invasion of French North Africa, that was known Operation Torch.^[1] The most important training aspect of those preparations was a naval fire-fighting course, and a practice-landing course.^[1]

Rosneath House became the locus for planning Operation Torch.^[3] In November and December 1942, the 29th Seabees arrived to continue maintenance and construction in preparation for Operation Torch.^[1] The Seabees completed the marine railway, provided 20 Nissen huts for barracks, eight 10000 barrel fuel tanks with a pumping station and fuel lines. They also built a laundry and roads to service the area as well as renovating a number of buildings to provide a hospital and admin offices.^[1]

The Green Isle area of Rosneath which was heavily wooded area, provided ideal cover for a military camp^[5] that was capable of billeting 4500 men, who were part of the operation.^[3] Naval personnel who couldn't be billeted on site, numbering 6300 officers and men, stayed with families in Helensburgh.^[3] British commandos who were part of the combined operation also stayed in Helensburgh.^[3]

Once Operation Torch was completed, the base was returned to the Royal Navy on 1 February 1943, except for the facilities needed for US Submarine Squadron 50 which continued to operate, dock space for USS Beaver and the Seabee camp^[3] at Clachan House^[6] in Rosneath. All the American personnel were transferred to the Springtown base in Derry, except for the 230 Civil Engineer Corps.^[1]

Receiving station

On the 20 August 1943, the base was again reactivated by the United States Navy, to act as the main receiving station for personnel who needed to be assigned to a specific vessel or location.^[1] During that year, up until August 1944, thousands of men arrived from the US, to be transferred to duties on ships and naval bases that were located all over the United Kingdom.^[1] The base provided training, supply and maintenance crews for increasingly larger units as the war progressed, including the 11th Amphibious Force consisting of 1900men. Other units were also supported that consisted of over 5000 sailors.^[1]

Decommissioning

On 5 May 1945, the base was decommissioned by the US Navy and in June 1945 the Seabees left.^[3] In 1948, the base was finally decommissioned by the Royal Navy.^[3] At some point after the end of the war, the base was demolished to be replaced by new housing, a school and a church.^[3] Little evidence of the base remains.^[3]

Facilities

The wharf at the base measured 4750 lineal feet of deep-water berths as well as 1500 lineal feet of shallow-water berths.^[1] The base also included:

64 dolphin berths for Landing Craft Mechanized craft.
A calibration and ship degaussing slipway.
A marine railway for amphibious landing craft.
An ammunition dump.
21 storage warehouses.
11, 10000 barrel fuel oil tanks.
10, 14400 gallon gasoline tanks.
153 air-raid shelters.
Housing and facilities for 4500 men on-site.
10 miles of road.
1400 piles of between 65 and 80 feet and 400 piles of between 80 and 90 feet were used for the wharf and pier.

Slightly north of Rosneath was Camp Clachan that consisted of barracks and facilities for 400 men and used to house the 29th Seabees.^[1] In the two months between April and May 1942, 325 Americans, 1000 Irish and 250 British construction workers worked on the constructing the camp.^[1] By June 1942, the base construction was well advanced.^[1] Huts at the base were divided into units, served from a single galley, with 500 men to a unit and 10 men per hut.^[1] Huts were placed in an irregular manner amongst the trees, interspersed with bomb shelters. A hospital was also constructed on a hillside overlooking the Firth of Clyde and contained 680 beds, designed in a fan shape with a galley at the centre.^[1] Portkil Hotel and cottage were repaired to use as accommodation.^[1] On the opposite side of the peninsula, approximately 3 miles from Rosneath, ammunition was stored in 14 stores measuring 20 x 50 feet.^[1]

United States Naval Construction Battalions, better known as the Navy Seabees, form the U.S. Naval Construction Force (NCF). The Seabee nickname is a heterograph of the initial letters "CB" from the words "Construction Battalion". Depending upon context, "Seabee" can refer to all enlisted personnel in the USN's occupational field 13 (OF-13), all personnel in the Naval Construction Force (NCF), or Construction Battalion. Seabees serve both in and outside the NCF. During World War II they were plank-holders of both the Naval Combat Demolition Units and the Underwater Demolition Teams (UDTs). The men in the NCF considered these units to be "Seabee". In addition, Seabees served as elements of Cubs, Lions, Acorns and the United States Marine Corps. They also provided the manpower for the top secret CWS Flame Tank Group. Today the Seabees have many special task assignments starting with Camp David and the Naval Support Unit at the Department of State. Seabees serve under both Commanders of the Naval Surface Forces Atlantic/Pacific fleets as well as on many base Public Works and USN diving commands.

<span class="mw-page-title-main">Seabees in World War II</span> Military unit

When World War II broke out the United States Naval Construction Battalions (Seabees) did not exist. The logistics of a two theater war were daunting to conceive. Rear Admiral Moreell completely understood the issues. What needed to be done was build staging bases to take the war to the enemy, across both oceans, and create the construction force to do the work. Naval Construction Battalions were first conceived at Bureau of Yards and Docks (BuDocks) in the 1930s. The onset of hostilities clarified to Radm. Moreell the need for developing advance bases to project American power. The solution: tap the vast pool of skilled labor in the U.S. Put it in uniform to build anything, anywhere under any conditions and get the Marine Corps to train it. The first volunteers came skilled. To obtain these tradesmen, military age was waived to age 50. It was later found that several past 60 had managed to get in. Men were given advanced rank/pay based upon experience making the Seabees the highest paid group in the U.S. military. The first 60 battalions had an average age of 37.
