29 Sept 1940 // HM Yacht Sappho vanished, almost certainly the victim of a mine, while on a night patrol in Falmouth Bay. An explosion was heard at 20:33 and debris was seen next morning, but there were no survivors from her 32 crew and no further trace was found. #RoyalNavy #WW2 #NavalHistory

29 Sept 1808 // 14-gun brig HMS Maria encountered a 22-gun French corvette off Guadeloupe and fought fiercely until overcome by the corvette's heavier broadside and more numerous crew. Six men were killed including Maria's commander, Lt James Bennett, and nine were wounded. #RoyalNavy #NavalHistory

29 Sept 1696 (O.S.) // 10-gun HMS Portsmouth's Pride (ex French la Joyeuse, captured 1694) was carrying letters to Admiral Benbow off the Norfolk coast but was pursued by a squadron of five French ships. After a short chase and a brief exchange of fire she surrendered. #RoyalNavy #NavalHistory

9 years ago today my 1st novel was published. It went on to be a bestseller, and earn over 800 reviews, averaging 4.4* Now I have 7 published and another coming out on the 16th. All my books are based on lesser-known activities of the #RoyalNavy #mustreads #histfic

28 Sept 1956 // An accidental fire caused the loss of three minesweepers which were laid up under wooden shelters on Haslar Creek, Portsmouth. HMS Broadley was completely burned out, and HMS Bisham and HMS Edlington were so badly damaged that they were scrapped. #RoyalNavy #NavalHistory

28 Sept 1916 // HM Trawler Orsino, a Hull boat in naval service as a patrol vessel at Stromness, was sunk with gunfire by U-boat U.55 north of Strathy Point on the north coast of Scotland. Six of her ten crew were lost, the other four became prisoners in Germany. #RoyalNavy #WW1 #NavalHistory

28 Sept 1808 // 16-gun brig HMS Seaflower was captured by French frigate Manche off Sumatra after a chase that had begun at 10am on the previous day. When the frigate caught up at noon, the brig surrendered, having thrown all but two of her guns overboard during the chase. #RoyalNavy #NavalHistory

The loss was blamed on the incompetence of the pilot, who had also run her ashore twice on the previous day. On the first occasion she had floated free and on the second she was hauled off, but her timbers had been weakened and the third grounding caused terminal damage. #RoyalNavy #NavalHistory

28 Sept 1799 // 14-gun schooner HMS Fox was driven onto a reef by a squall and wrecked in Saint George Sound, on the Gulf of Mexico coast of Florida. Her crew reached Dog Island where they managed to survive for over a month before rescue came, and no lives were lost. #RoyalNavy #NavalHistory

Shots from her pursuer left most of the Falcon's sails and rigging in tatters. A heavy sea was running, and her lee ports were underwater making the guns on that side unusable. She could offer little resistance and when the privateer called on her to surrender she complied. #RoyalNavy #NavalHistory

28 Sept 1686 (O.S.) // 44-gun 4th-rate HMS Half Moon Prize, in ordinary at Chatham, was destroyed by a fire which apparently began when a candle was knocked over in the cook's cabin. The only casualty was the cook, who was rescued in an unconscious state but did not recover. #RoyalNavy #NavalHistory

In total, if called upon for a high-intensity crisis or strike group deployment, the Royal Navy can generally mobilize 1 carrier and 4 to 6 escort combatants (destroyers and frigates combined) without compromising all baseline home-waters security commitments. #royalnavy

A small correction is necessary, it seems.
According to both their log-books, HMS Hood and HMS Repulse set sail 28 September 1923.

27 Sept 1944 // Destroyer HMS Rockingham (ex USS Swasey) struck a British mine off Aberdeen while acting as a target ship for aircrew training. She sank while under tow, with all on board being taken off by HMS Vanity and HMS Lancaster. (Imperial War Museum image FL 12226) #RoyalNavy #WW2

27 Sept 1943 // Destroyer HMS Intrepid capsized and sank in Lakki harbour on the island of Leros after being hit by two bombs from German dive bombers during intense German air attacks on the harbour. Fifteen of her crew lost their lives. (Imperial War Museum: A 7871) #RoyalNavy #WW2 #NavalHistory

Hit by two torpedoes soon after 1am, she lost power and flooded heavily. She was abandoned after damage control failed, and was scuttled by HMS Jasmine using gunfire and depth charges. She lay awash for some time and finally sank at about 7pm. 32 men were lost. #RoyalNavy #WW2 #NavalHistory

27 Sept 1840 // A large fire broke out at Plymouth Dockyard and HMS Talavera (74 guns) and HMS Imogene (28 guns) were destroyed, happily with no lives lost. Image: Thomas Lyde Hornbrook, 'Dockyard Fire at Plymouth' 1840 (North East Lincolnshire Museum via Wikimedia Commons). #RoyalNavy #NavalHistory
