HMS Ramillies (pennant number: 07) was one of five Revenge-class battleships built for the Royal Navy during World War I. She was completed after the Battle of Jutland in 1916 and saw no combat during the war. She served with the Grand Fleet for the duration of the war. The ship was active throughout World War II, with service ranging from convoy escort to shore bombardment to engaging enemy battleships.

Design and description
The Revenge-class ships were designed as slightly smaller, slower, and more heavily protected versions of the preceding Queen Elizabeth-class battleships. As an economy measure they were intended to revert to the previous practice of using both fuel oil and coal, but First Sea Lord Jackie Fisher rescinded the decision for coal in October 1914. Still under construction, the ships were redesigned to employ oil-fired boilers that increased the power of the engines by 9,000 shaft horsepower (6,700 kW) over the original specification.
Ramillies had a length overall of 620 feet 7 inches (189.2 m), a beam of 101 feet 5.5 inches (30.9 m) and a deep draught of 33 feet 7 inches (10.2 m). She had a designed displacement of 30,400 long tons (30,900 t) and displaced 33,570 long tons (34,109 t) at deep load. She was powered by 2 sets of Parsons steam turbines, each driving two shafts, using steam from eighteen Babcock & Wilcox boilers. The turbines were rated at 40,000 shp (30,000 kW) and intended to reach a maximum speed of 23 knots (42.6 km/h; 26.5 mph). During her sea trials on 1 October 1917, the ship only reached a top speed of 21.5 knots (39.8 km/h; 24.7 mph) from 42,414 shp (31,628 kW). She had a range of 7,000 nautical miles (12,964 km; 8,055 mi) at a cruising speed of 10 knots (18.5 km/h; 11.5 mph). Her crew numbered 936 officers and enlisted men in 1917. Her metacentric height was 4.5 feet (1.4 m) at deep load.
The Revenge class was equipped with eight breech-loading (BL) 15-inch (381 mm) Mk I guns in four twin gun turrets, in two superfiring pairs fore and aft of the superstructure, designated 'A', 'B', 'X', and 'Y' from front to rear. Twelve of the fourteen BL 6-inch (152 mm) Mk XII guns were mounted in casemates along the broadside of the vessel amidshipsl; the remaining pair were mounted on the shelter deck and were protected by gun shields. The ship also mounted four 3-pounder (47-millimetre (1.9 in)) guns. Her anti-aircraft (AA) armament consisted of two quick-firing (QF) 3-inch (76 mm) 20 cwt Mk I[Note 1] guns. She was fitted with four submerged 21-inch (530 mm) torpedo tubes, two on each broadside.
Ramillies was completed with two fire-control directors fitted with 15-foot (4.6 m) rangefinders. One was mounted above the conning tower, protected by an armoured hood, and the other was in the spotting top above the tripod foremast. Each turret was also fitted with a 15-foot rangefinder. The main armament could be controlled by 'X' turret as well. The secondary armament was primarily controlled by directors mounted on each side of the compass platform on the foremast once they were fitted in June 1918. A torpedo-control director with a 15-foot rangefinder was mounted at the aft end of the superstructure.
The ship's waterline belt consisted of Krupp cemented armour (KC) that was 13 inches (330 mm) thick between 'A' and 'Y' barbettes and thinned to 4 to 6 inches (102 to 152 mm) towards the ship's ends, but did not reach either the bow or the stern. Above this was a strake of armour 6 inches thick that extended between 'A' and 'X' barbettes. Transverse bulkheads 4 to 6 inches thick ran at an angle from the ends of the thickest part of the waterline belt to 'A' and 'Y' barbettes. The gun turrets were protected by 11 to 13 inches (279 to 330 mm) of KC armour, except for the turret roofs which were 4.75–5 inches (121–127 mm) thick. The barbettes ranged in thickness from 6–10 inches (152–254 mm) above the upper deck, but were only 4 to 6 inches thick below it. The Revenge-class ships had multiple armoured decks that ranged from 1 to 4 inches (25 to 102 mm) in thickness. The main conning tower had 13 inches of armour on the sides with a 3-inch roof. The torpedo director in the rear superstructure had 6 inches of armour protecting it. While under construction Ramillies was fitted with an anti-torpedo bulge that ran the length of the ship between the fore and aft barbettes. It was divided into water-tight empty outer compartments and inner compartments filled with water-tight "crushing tubes" intended to absorb and distribute the force of an explosion. The space between the tubes was filled with wooden packing. In addition, 1 inch of high-tensile steel was added to the main deck over the magazines and additional anti-flash equipment was added in the magazines.
The ship was fitted with flying-off platforms mounted on the roofs of 'B' and 'X' turrets in 1918, from which fighters and reconnaissance aircraft could launch. During the 1933–34 refit, the platforms were removed from the turrets and a catapult was installed on the roof of 'X' turret, along with a crane to recover a seaplane.
The existing rangefinders in 'B' and 'X' turrets were replaced by 30-foot (9.1 m) models in 1919–21 and her anti-aircraft defences were upgraded by the replacement of the original three-inch AA guns with a pair of QF four-inch (102 mm) AA guns during a short refit in 1924. Ramillies was refitted in 1926–27, when her bulge was extended above her waterline and the "crushing tubes" were removed from most of the lower bulge. An additional pair of four-inch AA guns were added, the six-inch guns from the shelter deck were removed and a simple high-angle rangefinder was added above the bridge.
During a more extensive refit in 1933–34, a High-Angle Control System (HACS) Mk I director replaced the high-angle rangefinder on the spotting top and another replaced the torpedo director aft. A pair of quadruple mounts for Vickers .50 machine guns were added abreast the conning tower and the mainmast was reconstructed as a tripod to support the weight of the second HACS. In addition the aft pair of torpedo tubes were removed. By June 1938 the single mounts of the AA guns were replaced by twin mounts, the forward torpedo tubes were removed, a radio-direction finding office was added and the catapult was removed.
Wartime modifications for the Revenge-class ships were fairly minimal. By 1943 Ramillies was fitted with a Type 279 early-warning radar, a Type 273 surface-search radar, a Type 284B gunnery radar for the main guns, a pair of Type 285 anti-aircraft gunnery sets and two Type 282 radars for the "pom-poms". A Type 650 radio-guided missile jammer was added before June 1944. Two four-barrel "pom-poms" were added in late 1941 atop 'B' and 'X' turrets as well as ten 20 mm Oerlikon guns that replaced the quadruple .50-caliber mounts. To save weight and make more room available for the additional crew required to man the new equipment like the radars and Oerlikons, four 6-inch guns were removed in 1943. In April of that year 10 more Oerlikons were added and an additional three in 1944/45.
Construction and service
Ramillies, named after the 1704 Battle of Ramillies, was laid down by William Beardmore and Company at its shipyard in Dalmuir, Scotland. She was launched on 12 June 1916 and commissioned on 1 September 1917. Commissioning was delayed because her rudder was damaged during launch. She was towed with great difficulty to the Cammell Laird works on the River Mersey for repairs.
Because of an increasing awareness of the danger of torpedo attack from submarines and destroyers, Ramillies, being completed later than her sisters in this class, had anti-torpedo bulges fitted. These were streamlined external compartments fitted along the waterline and filled with various shock absorbent materials, designed to take the impact of a torpedo before it could breach the hull.
Ramillies joined the 1st Battle Squadron of the Grand Fleet in May 1917.
In 1924 Ramillies joined the 2nd Battle Squadron of the British Atlantic Fleet. During the 1926 general strike she was sent to the River Mersey to land food supplies, along with HMS Barham. By late 1926 she was with the Mediterranean Fleet.
During the interwar period, Ramillies was lightened by having crushing tubes, wood and cement filling removed from her anti-torpedo bulges. By 1928, her anti-aircraft defences had been altered to four-4" quick firing Mark IV guns and her two forecastle deck 6" guns were removed.
When political disturbances broke out in Palestine in 1929, Ramillies was sent out to support the British presence.
From June 1932 to August 1934 she was in Plymouth for a major refit.
Old Empire, old ship
During 1937, Ramillies had her anti-aircraft batteries changed to 8 × 4-inch (102 mm) quick-firing Mark XVIs arranged in dual mountings. Two eight barrelled 2 pdr "pom-pom" anti-aircraft gun mounts were added as well.
Ramillies lost her torpedo tubes before the outbreak of World War II and had her aircraft catapult removed.
It was found to be more difficult to modernise the Revenge-class battleships than the Queen Elizabeth class (e.g. HMS Valiant), since the smaller displacement and narrower hull prevented the installation of larger machinery to increase speed - perhaps the greatest need.
The new and modernised Japanese battleships under construction in the 1930s made 24 to 27 knots (44 to 50 km/h), while the modernised Italian ships made 26 to 28 knots (48 to 52 km/h) and the new Littorio class made 30 knots (56 km/h). The German "pocket battleships" could achieve 28 knots (52 km/h), while the battleships/battlecruisers Scharnhorst and the Gneisenau made 32 knots (59 km/h) and the Bismarck and the Tirpitz made 29 knots (54 km/h). By 1939, Ramillies' design speed of 23 knots (43 km/h) could no longer be achieved with her old machinery. Often 18 knots (33 km/h) was her top speed, although in an emergency she could sometimes make 20 knots (37 km/h).
This put the Royal Navy in a difficult spot. When Ramillies and her sisters were in a battle fleet, the entire group was reduced to their top speed. This enabled faster Italian fleets to choose whether to engage and, if battle loomed, to manoeuvre to their advantage. Had they been faced by superior Japanese forces, the British would have been too slow to get away.
When on convoy protection duty and attacked by enemy battleships, Ramillies was too slow to pursue or to gain the most favourable position. However, her 15-inch (381 mm) guns were still lethal, and changed the course of events on several occasions.
Obsolete but needed
Despite her age, she gave useful service in the Second World War, doing everything from engaging enemy battleships to convoy escort to shore bombardment. Ramillies illustrated the value of an old capital ship for its deterrent effect, making technically superior enemy vessels decide not to attack for fear of sustaining damage while in British-controlled seas, far from any repair bases. Ramilles and her sister Royal Sovereign, were in materially far better condition than the other sister ships Revenge and Resolution, even though they lacked the partial modernization given to the fifth sister, Royal Oak. This is further illustrated by the fact that both Ramilles and Royal Sovereign were given partial modernization, radar enhancements and augmentation of their anti-aircraft weapons during 1942 and 1943 while the other two sisters had been withdrawn from service by the end of 1943 and placed into reserve with the subsequent removal of their 15" main batteries.
Outbreak of the Second World War
The outbreak of war found Ramillies as part of the British Home Fleet based at Scapa Flow. She participated in a sweep of the waters between Iceland, Norway and Scotland from 31 August to 7 September 1939 with a mission to intercept German merchant ships trying to return home before the start of the war.
In late 1939 Ramillies sailed for the East, with a stint in the Indian Ocean, when HRH Prince Philip was a crew member. She visited New Zealand over Christmas 1939 and from 6 January 1940 to 12 February she escorted 13,000 New Zealand troops from Wellington to Suez. From 15 April to 7 May 1940 she escorted Australian soldiers from Melbourne to Suez.
But before this she was diverted from escort duties when the Admiralty became aware of the presence of the German "pocket battleship" Admiral Graf Spee in the Indian Ocean off Lourenço Marques (current Maputo, Mozambique) on 16 November 1939. Ramillies was detached at Aden and formed 'Force J' along with the battleship HMS Malaya, and the aircraft carrier HMS Glorious. The ships were sent south to intercept the German raider, but Graf Spee sailed back into the South Atlantic where she was brought to action in the Battle of the River Plate off Montevideo by 'Force H', the cruisers HMS Ajax and HMS Achilles, joined by HMS Exeter from 'Force G'.
After Italy's entrance into the war in June 1940, Ramillies served in the Mediterranean. Along with Royal Sovereign, she escorted a convoy from Alexandria, in Egypt, to Malta between 27 and 30 June 1940. From 16 to 18 August she bombarded the port of Bardia and Fort Capuzzo in the Italian colony of Libya in North Africa. On the way back she was attacked by Italian aircraft, but was not hit. She was a part of Admiral Andrew Cunningham's Mediterranean fleet, 'Force D', based at Alexandria.
Ramillies escorted a convoy from Alexandria to Malta between 8 October and 14 October 1940. On the way back, the ships were attacked by eight Italian torpedo boats. There were no British losses, but three of the Italian boats were sunk and four damaged by the light cruiser HMS Ajax.
From 25 to 28 October 1940, Ramillies escorted a convoy bound from Alexandria to Crete. In the period 10 to 13 November she was on convoy escort duty from Alexandria to Malta, and then went on to Crete. During this time an enemy submarine spotted Ramillies and fired torpedoes but did not hit her.
The Royal Navy's attack on the main Italian naval force at Taranto, on 11 November 1940, reduced the Italians to two serviceable battleships. Cunningham was then able to release to North Atlantic convoy duty his oldest and slowest battleships, the Ramillies and the Malaya, thus freeing up escort destroyers in the Mediterranean.
Ramillies steamed west with the Mediterranean fleet in late November 1940, forming part of the escort for four merchant ships bound for Malta with much needed supplies. When she was in the central basin of the sea, she broke off from the rest and headed west.[clarification needed]
Accompanied by the cruisers HMS Berwick and HMS Newcastle, she steamed through the Sicilian Narrows. Newcastle had been in Malta for several days, where she had landed 15,000 US gallons (57,000 l; 12,000 imp gal) of aviation fuel, 40 Hawker Hurricane engines and 300 RAF technical personnel. They were to join up with 'Force H' from Gibraltar under Admiral James Somerville which was in the area escorting three large fast merchant ships heading east, two for Malta and one for Alexandria. They would turn the escort duties over to Admiral Cunningham at a rendezvous point and make haste out of the danger area and return to Gibraltar. Ramillies was making her best possible speed of 20 knots (37 km/h) running the gauntlet nicknamed "Bomb Alley".
Admiral Somerville had the aircraft carrier HMS Ark Royal somewhat behind the rest of the force, his flag in the old battlecruiser HMS Renown, along with the cruisers HMS Sheffield, HMS Manchester and HMS Despatch and five destroyers. At 10:40 am on 27 November 1940, a scouting plane from the Italian cruiser Bolzano reported a force of one battleship, two cruisers and four destroyers north of Bône, Algeria. Italian Admiral Inigo Campioni was at sea with two battleships, six heavy cruisers and fourteen destroyers. His orders were to attack only if faced by a decisively inferior enemy. With a two-to-one superiority in capital ships, he had his opportunity and altered course to intercept. His force was centred around the new and powerful battleship Vittorio Veneto and the modernised battleship Giulio Cesare. This was a dangerous situation for the British.
Somerville became aware of the peril from the Italian fleet and sent his convoy off to the southeast with a small escort. He pushed ahead to rendezvous with the Ramillies and the Berwick, so as to get between the Italians and the convoy. The odds favoured the Italians, since Ramillies was slow and her guns were outranged by the Italians. In addition Somerville's ships were within easy range of shore based enemy aircraft. But, his object was to get the convoy safely to Malta, so he charged ahead at the Italians. He also sent his cruisers out front under Vice-Admiral Lancelot Holland, keeping his two slower capital ships further back screened by destroyers. The Ark Royal was well behind with two escorting destroyers. Campioni, after hearing of the presence of another British capital ship and an aircraft carrier, decided not to risk Italy's only two serviceable capital ships and after a brief exchange of gunfire at long range, in which Ramillies got off several salvoes, the Italians turned away and made for Naples. Berwick was damaged in the engagement, as was one Italian destroyer.
The engagement was called the Battle of Cape Spartivento.
The North Atlantic: Scharnhorst, Gneisenau and Bismarck
Ramillies was assigned to North Atlantic convoy duty on her return to Britain. This was a critical assignment as the British Empire and Dominions were now alone, losses to submarines were high, and the home country was in immediate danger of being starved into submission. Should German surface raiders, whether converted merchantmen or regular surface combatants including full-sized battleships, break out and destroy a British convoy, it might be sufficient to tip the balance. Across this ocean came food, rubber, lumber, mineral ores, weapons and munitions from Australia, New Zealand, South East Asia, South Africa, South America, Canada and the United States; there was also oil from Venezuela and the Middle East and troops from India and Canada. One decimated troop convoy might lead Canada and the other dominions to stop moving troops across the Atlantic. Outward bound were men, munitions and aircraft for East Africa, the Middle East, India and the Far East.
On 12 January 1941, Ramillies left Britain as escort for 40,000 troops in a large convoy from Britain, south past the danger zone to West Africa. They were bound for the Middle East.
Ramillies was on duty in the North Atlantic Ocean escorting Convoy HX 106, some 41 ships, eastbound from Halifax, Nova Scotia to Liverpool, England when on 8 February 1941 the two new German battleships, Scharnhorst and Gneisenau, appeared over the horizon. The German squadron was under the command of Admiral Günther Lütjens. The captain of the Scharnhorst offered to draw off the Ramillies, so that the Gneisenau could sink the merchant ships. It is unlikely, however, that Ramillies' captain would leave the convoy he was protecting to chase the much faster German ship. Further, Ramillies was armed with the excellent 15 inch gun and was capable of doing significant damage to the German vessels. In the event, Lütjens strictly followed Adolf Hitler's directive not to engage enemy capital ships. The presence of Ramillies was sufficient to deter the attack.
On 24 May 1941, Ramillies, with Captain Arthur D. Read commanding, was south of Cape Farewell, Greenland, on duty escorting Convoy HX 127 eastbound from Halifax. Some 57 merchant ships were in the group bound for Liverpool, with the most common cargoes being, oil, aviation spirit, lubricants, gasoline, lumber, grain, steel, sugar, scrap iron and pig iron. Two ships carried general cargo, and there were single ships carrying molasses, trucks and cereals. Other escort vessels were designed to meet the submarine menace, and included a modern Canadian destroyer, HMCS Ottawa, the Indian navy sloop, HMIS Sutlej, an obsolete ex-US Navy destroyer, HMS Salisbury, an escort destroyer, HMS Hambledon, the corvettes HMS Larkspur, HMS Begonia and several other smaller ships. If anything, Ramillies would have been a liability dealing with submarines. She was there as insurance against attack by surface raiders.
If Ramillies had to face a major surface attack, the two destroyers were probably the only escorts of value to her.
The new German battleship Bismarck broke out into the North Atlantic after sinking the battlecruiser HMS Hood, Britain's largest warship, in the Battle of the Denmark Strait. Ramillies was well east of Newfoundland to the southwest of Bismarck, and if she had continued her raid, Ramillies was all that the Royal Navy had to stop her from ravaging the sealanes off North America. On 24 May 1941 the Admiralty ordered Ramillies to leave the convoy and steam on a course to intercept the enemy ship. Bismarck had sustained some damage in the action against the Prince of Wales, and opted to make for France for repairs, instead of continuing on a convoy raiding mission.
It was a measure of the desperation of the Royal Navy that such an old ship was sent out alone to intercept one of the world's most potent battleships which was supported by the heavy cruiser Prinz Eugen. Fortunately for her, she was not put to the test.
Another typical assignment was to provide ocean escort to Convoy HX 130, bound for Liverpool with 45 merchant ships. Ramillies joined the convoy just outside Halifax harbour at 1530 hours on 1 June 1941 and remained with the ships till 9 June at 53 30 north and 46 48 west, the mid-ocean meeting point, where an escort from Britain took over.
Return to the Indian Ocean
Ramillies was a part of a British fleet put together hurriedly in March 1942 under Admiral James Somerville in an attempt to prevent Japanese naval forces from cutting the sea lanes to India. The scratch fleet consisted of two aircraft carriers and three old Revenge-class battleships. They did not encounter the main part of the Japanese fleet, which withdrew after causing great destruction to Allied shipping, including sinking an aircraft carrier and several other smaller warships.
In May 1942 Ramillies was still in the Indian Ocean; she was sent to cover the Allied invasion of Madagascar. On 29 May, a reconnaissance plane from the Japanese submarine I-10 spotted Ramillies at anchor in Diego Suarez harbour. The battleship changed her berth after the plane was seen. However, the Japanese submarines I-16 and I-20 launched two midget submarines, one of which, commanded by Lieutenant Saburo Akieda, managed to penetrate the harbour and to fire its two torpedoes. The first severely damaged Ramillies at about 20:25; the second sank the oil tanker British Loyalty at 21:20. Lieutenant Akieda came under depth charge attack from the corvettes HMS Genista and HMS Thyme but managed to beach his submarine and flee inland with Petty Officer Masami Takemoto. Both were killed in a firefight with Royal Marines three days later.
Ramillies was reported sunk by the Japanese, but in fact was merely severely damaged. She was towed to Durban for temporary repairs, then in August 1942 she returned to Plymouth under her own steam and was back in service in June 1943. The Royal Navy's senior constructor was sent out to Madagascar to assess the damage inflicted by the torpedo. His report noted that even though the ship was almost 30 years old, she had withstood severe damage that would have likely sunk a newer ship and her survival was a testament to her original sound construction and design.
While in drydock, an additional 2-inch (51 mm) of steel was added to the main deck over the magazines. This reflected the lessons from the sinking of the Hood as well as of the effectiveness of dive bombers at the Battle of Midway. Four 6-inch (152 mm) guns were replaced by two more four-barrelled anti-aircraft pompoms, this reflected the awareness of the greater risk posed by aircraft than by smaller surface vessels. It was ironic that Ramillies faced such a surface attack later in the war. Fortunately the remaining 6-inch (152 mm) guns were sufficient to handle it.
D-Day and the south of France
Ramillies provided fire support for the Normandy Landings on 6 June 1944. Sword Beach, to the east, was her assigned area; she was given the primary task of silencing the Berneville battery. The ship began by opening fire on the 6" (152 mm) battery, knocking out four of the six guns in the first 80 minutes and keeping the attention of the rest, allowing landing craft to proceed unmolested. By evening she had accounted for the other two guns.
During the course of the first day, she repelled an attack by two German destroyers which fired five torpedoes at her, all missing. She also drove off a pack of E boats with her secondary 4- and 6-inch (102 and 152 mm) guns. That evening she returned to Portsmouth and reammunitioned the next day. She was back off Normandy on 8 June 1944 and knocked out another 6" battery.
On 9 June, Ramillies, directed by forward observation posts, fired on German tanks, guns, infantry concentrations and motor vehicles with great success, breaking up units before they could launch counterattacks. She also beat off an attack by German E-boats.
On 10 June, she hit enemy railway marshalling yards near Caen, many miles inland.
The following day, Ramillies hit a concentration of 200 enemy tanks, inflicting a lot of damage. That night she bombarded more railway marshalling yards.
On 12 June she suffered a near miss when attacked by a dive bomber.
A German mobile artillery unit fired 32 rounds at Ramillies on 15 June, of which two hit the ship. One crew member was wounded in the leg. Ramillies moved out of range and continued her bombardment. On 16 June she continued her bombardment and on 17 June she hit a mobile battery.
In the course of her Normandy engagement, she fired 1,002 15-inch (381 mm) shells, thought to be the greatest bombardment by any single ship up to that time.
Ramillies was put in reserve on 31 January 1945 at Portsmouth and was used as an accommodation ship. John Egerton Broome was captain from 1945 to 1946. She was sold in 1946 and scrapped in 1949. One of Ramillies' 15-inch (381 mm) guns has been preserved and can be seen at the Imperial War Museum in London. The ship's bell is preserved at HMCS Star, a Naval Reserve Division at Hamilton, Ontario, Canada.
