Hugh Mackenzie (Royal Navy officer)

Hugh Stirling Mackenzie was born in Inverness, Scotland, on 3 July 1913, the son of Dr Theodore Charles Mackenzie, the medical superintendent of the Inverness District Asylum, and his wife, Margaret (Madge) Wilson. His home, and birthplace, was Ruigh-Ard, the superintendent's residence. He had two older brothers, Charles and Alec, and a younger sister, Margaret. At the age of nine, he was sent to Cargilfield Preparatory School, where his brother Charles was head boy, followed by his brother Alec the next year. In 1924, he appeared before the interview board and was given a medical examination as the first steps to admission to the Royal Naval College, Dartmouth. He was initially rejected on the grounds of deficient eyesight, but his father lodged an appeal, and had his sight examined by an eye specialist in Edinburgh, who declared that it met the Navy's standards. Another test at Queen Anne's Mansions in London cleared the way for him to sit the entrance examinations, which he passed. == Early naval career ==

Mackenzie entered the Royal Naval College in January 1927, one of 51 members of the Anson Term, three of whom would not graduate in July 1930. They then received leave that lasted until September, which Mackenzie spent at home with his parents and three siblings at Ruigh-Ard. Due to cutbacks, there was no Cadet Training Cruiser for the class, and they were posted to the fleet for additional training. Mackenzie was posted to the battleship , part of the Mediterranean Fleet's 1st Battle Squadron. He embarked for the Mediterranean on the P&O ocean liner , on which the new fleet commander, Admiral Sir William Wordsworth Fisher, was also travelling, completing the voyage on the battleship . In addition to service on Ramillies, Mackenzie, who was promoted from officer cadet to midshipman on 1 May 1931, spent a fortnight on the aircraft carrier and three months on the destroyers and in the summer of 1932 in order to gain familiarity with the work of various ships of the fleet. At the conclusion of his tour of duty in the Mediterranean in July 1933, Mackenzie passed his sub lieutenant's examination, and returned to England on the destroyer to rejoin the Anson Term for the six-month sub lieutenant's course at the Royal Naval College, Greenwich. After coursework that was interrupted by an operation on his left inner ear at the Royal Naval Hospital, Chatham, the midshipmen moved on to specialist courses in gunnery, torpedo, navigation and signals at , , and . He was promoted to sub lieutenant, with seniority backdated to 16 March 1934. Not liking the life on battleships, he applied for submarine duty. He was accepted, and sent to in January 1935, where he was trained as a submariner. Mackenzie was posted to , one of the boats of the 4th Submarine Flotilla, which was based in Hong Kong as part of the China Station. During the summer, the flotilla moved north to Weihaiwei to escape the heat and humidity. He was promoted to lieutenant, with seniority backdated to 16 October 1935, and returned to England via Japan and the Trans-Canada Railway in August 1937. He joined the 2nd Submarine Flotilla, which was part of the Home Fleet, and based at Devonport. He was given command of HMS Mist, an old coal burner that was manned by spare crewmen assigned to the flotilla and commanded by the spare lieutenant. Soon after, the Mist was ordered to join the reserve fleet, into which she was reluctantly accepted. In May 1938, Mackenzie was assigned to . There was a serious incident when Seahorse was accidentally rammed by the destroyer . The submarine dived to avoid the destroyer, which did not detect it on asdic, but suffered damage to its periscopes. Both ships took several weeks to repair. == Second World War ==

Osiris In April 1939, Mackenzie was posted to . The boat was almost lost during a test dive when a rivet popped out. On 27 September 1939, Osiris sailed for Malta to join the 1st Submarine Flotilla. She embarked on her first war patrol on 31 May 1940, and was at sea when Italy declared war on the UK on 10 June 1940. On the night of 16 August, Osiris was on her third war patrol, attempting to interdict shipping between Italy and Albania, when she sighted a cargo ship off the Albanian coast. The ship, the Morea, was empty and riding high in the water. Two torpedoes were fired at range, but apparently passed beneath her. Osiris then closed to within and fired two more torpedoes, which also missed. She then surfaced and engaged Morea with her deck gun. Despite the brilliant flashes and considerable noise from the deck gun, there was no sign of activity on board, and shells were pumped into Morea until she started to sink. Osiris departed Malta for her next war patrol on 9 September 1940, returning to the same vicinity. She found the area rich with targets moving troops and supplies from Italy to Albania for what would soon be revealed to be the Italian invasion of Greece. Osiris attempted to engage them, but for one reason or another, a whole series of attacks failed. On 13 September, she fired two salvoes of two torpedoes each at a range of at a convoy of three ships escorted by destroyers; all missed. But on 22 September she fired a full six-torpedo spread at a convoy at range. At first the crew thought that the torpedoes had again missed; but then there was an explosion, and the Italian torpedo boat Palestro was sunk. It was Mackenzie's last patrol in Osiris. He received orders to return to England for the "Perisher", the five-week submarine Commanding Officers Qualifying Course. Because the Mediterranean was closed due to the war, he had to sail round the Cape of Good Hope in the . He was formally declared to have qualified for command of a submarine in February 1941, and assigned to the 7th Submarine Flotilla as a spare commanding officer. On 7 March 1941, he was given temporary command of an old boat used for training, . Heading down Lough Foyle in the early morning darkness on 10 March showing navigation lights, she encountered the heading in the opposite direction on the port (incorrect) side. As Lairdsbank approached the submarine, but without sighting it, she suddenly veered to starboard. Mackenzie ordered "full astern", but the two collided. Fortunately, although the bow of H28 was crumpled, the boat remained watertight, and Mackenzie was able to return to Derry for repairs. Lairdsbank suffered no damage and was unaware that there had been a collision. Admiral Max Horton told Mackenzie not to do it again. On 14 April, Mackenzie assumed command of another training boat, . Thrasher In June 1941, Mackenzie received orders to rejoin the Mediterranean Fleet. This time he travelled to Alexandria through the Mediterranean as a passenger on the submarine . On 12 October, he assumed command of the submarine . A few days later he set out on his first war patrol in her (but Thrashers fifth), sinking an Italian schooner with the deck gun, and unsuccessfully engaged an Italian minesweeper. On the next patrol, Mackenzie attacked a three-ship convoy on 25 November, sinking the Italian cargo ship Attilio Deffenu with a torpedo. Thrasher had orders to insert a party of Yugoslav agents under the command of Stanislav Rapotec, but the mission was cancelled and Thrasher returned them to Alexandria. Thrasher set out again in January 1942, and found a large ship with an escort. Failing to gain a firing position, Mackenzie surfaced, overtook them, and attacked, sinking the Italian cargo ship Fedora. He was made a Companion of the Distinguished Service Order on 30 June 1942, and was promoted to lieutenant commander on 23 October, with seniority of 16 October. He was awarded a bar to his Distinguished Service Order on 19 January 1943. He was sent on a publicity tour to increase public awareness of the role that submarines were playing in the conflict, and appeared in a war movie, We Dive at Dawn. Tantalus On 2 April 1943, Mackenzie assumed command of the submarine , a new boat which departed the builder's yard at Barrow-in-Furness on 31 May 1943. After a work-up patrol in the Norwegian Sea, == Post-war career ==

Mackenzie was posted to Derry, where he was part of a group of submariners in charge of about fifty German Type VII, Type IX and Type XXI U-boats that had surrendered. While there, he met Third Officer Helen Maureen Bradish-Ellames, a Women's Royal Naval Service officer who worked on the staff in Derry. In January 1946, with the war over, he became an instructor on the Perisher course. He was promoted to commander on 12 July 1946, with seniority of 30 June 1946. He married Maureen Bradish-Ellames on 10 August 1946; they had a son and two daughters. Mackenzie's next assignment was as commanding the Underwater Detection Establishment (UDE), a post normally held by an anti-submarine specialist rather than a submariner and was commander of the 1st Destroyer Squadron from June 1954 until December 1956. Rear Admiral Wilfrid Woods, and then Rear Admiral Bertram Taylor. On a visit to the United States, he was given a tour of the first nuclear-powered submarine, the . After that he became Captain of the Boys' Training Establishment at Shotley, Suffolk, in January 1959. He warned the Australian government that Britain could no longer afford to maintain submarines in Australia, and recommended that Australia acquire its own submarines, preferably nuclear-powered. The advice did not go down well, but within a few years the British boats were withdrawn, and the Royal Australian Navy acquired diesel-powered s to replace them. Mackenzie's tenure as Flag Officer Submarines was brief. On 26 December 1962 he was notified that he would be appointed the Chief Polaris Executive (CPE). He described this as "the most strenuous five years of my whole career, but also in the end the most satisfying, because of their direct contribution to the ultimate defence of this country." He established his office and that of his immediate staff in London, which he considered was necessary in order to be in immediate contact with the Admiralty, the Ministers, and the key departments. He was initially given two rooms and a closet at the Admiralty. Most of the Polaris Executive was located in Bath, Somerset, where the Admiralty's technical and logistics departments had been relocated in 1938. He was made a Companion of the Order of the Bath in the 1963 New Year Honours, promoted to vice admiral on 19 August 1964, and appointed a Knight Commander of the Order of the Bath in the 1966 Birthday Honours. The Polaris project was completed on time, with the first successful firing of a Polaris missile conducted off Cape Canaveral on 15 February 1968, and within budget. == Later life ==

Mackenzie retired on 20 September 1968. He was chairman of the Navy League of Great Britain from 1969 to 1974, and the director of the Atlantic Salmon Research Trust from 1969 to 1979, and was its chairman from 1979 to 1983. In July 1982, he was involved in a serious motor vehicle accident on the M1 motorway. An overtaking vehicle careened into the back of his car and knocked it off the road. The petrol tank ruptured and the car caught on fire. Despite burns to 15 per cent of his body, he was able to drag clear his wife Maureen, who suffered burns to 40 per cent of her body. Both were admitted to the burns unit at the Leicester Royal Infirmary. Mackenzie published his memoirs, titled The Sword of Damocles, in 1995. On 28 March 1996, he attended a ceremony at the submarine base at Faslane, to mark the decommissioning of , the last of the four s whose construction he had overseen in the 1960s. On 8 October 1996, he suffered a fatal heart attack at his home Puttenham, Surrey. A service of thanksgiving was held in Guildford Cathedral on 8 February 1997. His remains were cremated, and the ashes buried near Inverness. == Notes ==
