HMS Ben-my-Chree

SS Ben-my-Chree had a tonnage of 2,651 GRT.[5] The ship was 390 feet (118.9 m) long overall and 375 feet (114.3 m) long between perpendiculars. She had a beam of 46 feet (14.0 m) and a depth of 18 feet 6 inches (5.64 m) from her main deck to the top of her keel. Ben-my-Chree had five decks[6] and a capacity of 2,549 passengers with a crew of 119.[2]

The ship was powered by three license-built Parsons direct-drive steam turbines, each driving one propeller shaft. They were powered by steam provided by four cylindrical boilers at a working pressure of 170 psi (1,172 kPa; 12 kgf/cm²)[6] that gave her a speed of 24.2 knots (44.8 km/h; 27.8 mph). Her engines burnt up to 95 long tons (97 t) of coal a day, which made her an expensive ship to run.[2]

She was ordered in 1907 by the Isle of Man Steam Packet Company and was built at the Vickers shipyard in Barrow-in-Furness at a cost of GB£112,000. The ship was launched on 23 March 1908[2] and completed on 8 August.[5] Ben-my-Chree was normally laid up, because of her expense, except for the three busiest months of the year when she had a full complement of passengers.[2]

SS Ben-my-Chree was chartered by the Royal Navy on 1 January 1915 and she began her conversion into a seaplane carrier at the Cammell Laird shipyard in Birkenhead the following day. Part of her aft superstructure was removed and replaced by a hangar, aft of her rear funnel, that housed four to six seaplanes. The aircraft were lifted in and out of the water by derricks fore and aft. A dismountable 60-foot-long (18 m) flying-off platform was installed forward of her superstructure; it was equipped with a trolley and rails to allow a seaplane to take off.[3][5]

In RN service the ship displaced 3,888 long tons (3,950 t), was 387 feet (118.0 m) long overall, and had a draught of 16 feet (4.9 m). Ben-my-Chree's turbines generated 14,500 shaft horsepower (10,800 kW) and she was credited with a speed of 24.5 knots (45.4 km/h; 28.2 mph) although that speed was exceeded in service. The ship could carry 502 long tons (510 t) of coal. Her crew consisted of approximately 250 officers and enlisted men.[5]

Her armament consisted of four quick-firing (QF) 12-pounder 18 cwt guns,[Note 1] and two Vickers three-pounder AA guns.[5] Ben-my-Chree carried 130 rounds per 12-pounder and 64 rounds for each three-pounder. In May 1916, one 12-pounder AA gun, a three-pounder, and a 2-pounder pom-pom, each on army carriages, were added.[3][5]

She was initially assigned to the Harwich Force, under the command of Commander Cecil L'Estrange Malone, where on 3 May she took part in an abortive air raid on Norddeich that had to be abandoned because of thick fog.[7] On 6 May, while on another unsuccessful mission to attack Norddeich, she was accidentally rammed by the destroyer Lennox in thick fog, although damage was slight.[3] Another attempt was made on 11 May, but was again abandoned because of heavy fog.[7] During this raid, Ben-my-Chree attempted to launch her Sopwith Schneider from a trolley off the fore deck, but the engine backfired, wrecking its starter, and breaking the pilot's wrist as the starter handle was in the cockpit.[8]

To the Dardanelles

In May 1915, she sailed for the Dardanelles,[3] carrying two Short Type 184 torpedo bombers, and arrived at Lesbos on 10 June. Her aircraft were mainly involved in spotting for ships providing naval gunfire support for troops ashore, although they also conducted reconnaissance missions of the area. On 11 August, one of these missions had spotted a Turkish ship off the north coast of the Sea of Marmora and, on the following day, Flight Commander Charles Edmonds attacked it flying a Short 184 seaplane. He left his observer behind and flew with a reduced fuel load to lighten his aircraft enough to carry a 14-inch (356 mm), 810-pound (370 kg) torpedo. He successfully dropped his aerial torpedo at a distance of about 800 yards (730 m) and an altitude of 15 feet (4.6 m). It turned out that his target had been beached after having been torpedoed by the British submarine E14. This was followed by a successful attack on 17 August against a 5,000-long-ton (5,100 t) ship by Edmonds. Flight Lieutenant George Dacre accompanied Edmonds on his flight in his own aircraft, but suffered engine troubles and had to land in the Dardanelles. He was taxiing on the water when he encountered a large steam tugboat, which he promptly torpedoed. After taxiing for several miles he was able to get airborne again and was within gliding distance of Ben-my-Chree when his engine failed permanently.[9]

On 2 September, she helped to rescue Australian troops from the torpedoed troopship HMT Southland off Lemnos. The ship was transferred to Port Said, Egypt after the end of the Gallipoli Campaign.[3] Ben-my-Chree became the flagship of the East Indies and Egypt Seaplane Squadron when it was formed in January 1916.[4] The squadron was under the command of the General Officer Commanding, Egypt and its primary duty was to watch Turkish positions and movements in southern Palestine and the Sinai.[10] SS Uganda collided with her on 11 February and badly damaged the ship's bow.[3] Permanent repairs took were made at Suez from 13 March to 25 April.[4] Commander Charles Samson replaced L'Estrange Malone as captain on 14 May. A few days later, Lieutenant William Benn joined the ship as an observer.[11] Ben-my-Chree was based at Aden later in 1916.[12]

Loss

HMS Ben-my-Chree under fire

French troops occupied the Greek island of Kastellorizo, off the southwest coast of Turkey, on 20 December 1916 to use it as an advance base against the Turks. Not pleased at the presence of the French, the Turks secretly deployed an artillery battery of four 155-millimetre (6.1 in) and twelve 77-millimetre (3.0 in) guns within range of the island. The French commander requested a seaplane carrier to conduct reconnaissance in the area and Ben-my-Chree was sent in response. She arrived on 11 January 1917 and anchored in the harbour which faced the mainland. The Turkish guns opened fire about two hours later, hitting the carrier with their third shot. Subsequent shells disabled her steering and started a fire in her hangar that spread across her upper deck.[3] (See Mustafa Ertuğrul Aker)

HMS Ben-my-Chree sinking

The crew was ordered to abandon ship after about forty minutes of the bombardment using the only remaining operable motor lifeboat of the three stowed on board. One officer and four enlisted men were injured, but no one was killed. The Turks continued their bombardment for five hours until Ben-my-Chree listed to starboard and sank in shallow water. Later in the day, the captain and the chief engineer returned to the wreck to rescue the ship's mascots, a cat and dog which had both survived the attack.[13]

Ben-my-Chree's wreck remained in place until 1920 when it was refloated by the salvage ship Vallette and towed to the port of Piraeus. The ship proved to be a constructive total loss and was broken up in Venice, Italy in 1923.[14]

During her short career she operated Sopwith Type 860, Schneider, and Baby, as well as Short Type 830 and Type 184 floatplanes.[4]
