On this day in 1940, Swordfish torpedo bombers from HMS Illustrious launched a successful surprise attack against the Italian fleet at anchor at Taranto, disabling three battleships and damaging one heavy cruiser and two destroyers.

"Mussolini has become boastful; he has got into the habit of referring to the Mediterranean as ‘Mare Nostrum’, which means ‘our sea’. We are going to change all that ... we are going to change it to ‘Cunningham’s Pond’. I tell you that with no uncertain voice..."The Taranto Raid.

Fighting Napoleon’s Continental System: The Second Battle of Copenhagen (1807)

The city of Copenhagen was a familiar sight for some of the British sailors. In 1801, Nelson achieved one of his lesser-known victories here. At the time, Denmark had joined the League of Armed Neutrality, jeopardizing Britain’s vital imports of hemp, tar, and timber from Scandinavia—supplies critical for the Royal Navy.A painting of the British bombardment by Christoffer Wilhelm Eckersberg The year is 1807. Nelson has been dead for two years, but his legacy endures. The French lack the resolve and resources to challenge the British in another major open-sea engagement. The threat of invasion had faded.

The Birth of a Legend: The Construction of HMS Victory

The year is 1758, and the Seven Years' War has been raging around the world for nearly two years with no clear victor in sight. The Royal Navy was working tirelessly to deliver a decisive victory for king and country. On 14 July, Prime Minister William Pitt the Elder ordered the construction of 12 additional ships of the line to bolster the fleet, including one first-rater. A few days later, at Chatham Dockyard, construction began on a leviathan destined to change the course of history.HMS Victory, by Geoff Hunt When the keel of the Victory was laid down, no one could have predicted the name she would eventually bear—a name once marred by tragedy. The previous Victory, launched in 1737, was also a first-rate ship of the line. Unlike her successor, however, this Victory had a brief and ill-fated career. On the night of October 4–5, 1744, the massive battleship foundered during a violent storm in the English Channel.'Loss of HMS 'Victory', 4 October 1744' by Peter Monamy

Who was the boatswain in Nelson's time?
(1/8) The warrant officer with perhaps the most notorious reputation was the boatswain. The boatswain is perhaps one of the oldest attested ranks in the Royal Navy, with its history dating back to the days of the Anglo-Saxon ruler Edward the Confessor (r. 1042–1066 CE). The word derives from the Old English compound batswegen, consisting of the elements bat (‘boat’) and swain (‘apprentice, follower, servant, young man’).Image (2/8) Just like other warrant officers, the boatswain was appointed by a paper warrant from the Navy Board, instead of a commission on parchment issued by the Board of Admiralty and reserved for higher-ranking officers. In the time of Nelson, the boatswain was in charge of the boats, sails, colours, anchors, cables, and cordage. Having risen from the ranks of seamen, he was usually a man of respectable age, sourcing his vast knowledge on these matters from years of experience. Before receiving the warrant of boatswain, however, a one-year trial with the captain as a petty officer was obligatory. Another requirement was that he be literate, as per Admiralty Regulations, a rule obligatory for all warrant officers.A boatswain in his uniform of the era of King George IV, 1820s. NMM

HMS Collingwood (1882): A Brief History 🧵 Image At her conception, Collingwood was not intended as the prototype of a new class but rather as a one-off response by Sir Nathaniel Barnaby, Director of Naval Construction, to the French Amiral Baudin and Terrible-class ironclads. His final design echoed Devastation with fore-and-aft main armament in barbettes, set higher above the waterline, but the Admiralty altered it by lengthening the hull, adding horsepower for a 15-knot speed, and substituting smaller guns. These changes, along with lines taken from Colossus, increased displacement by 2,500 tons.Image

The Battle that Secured Greek Independence: The Battle of Navarino, 20 October 1827 🧵 Image The Battle of Navarino, fought on 20 October 1827, proved to be the decisive turning point of the Greek War of Independence. For much of the conflict, the Ottoman Empire, supported by its Egyptian vassal state, had managed to suppress the rebellion and seemed on the verge of crushing it altogether. At this moment, however, the three European powers—Britain, France, and Russia—intervened, dispatching fleets to the eastern Mediterranean. Their intervention culminated in the destruction of the Ottoman and Egyptian naval forces in what would become the last great fleet action fought entirely by sailing ships.Action at close quarters during the battle.

On 25 March 1807, the United Kingdom abolished the slave trade. More than two decades later, slavery was abolished altogether in the British Empire through the Slavery Abolition Act of 1833. More than 800,000 individuals were freed from slavery with immediate effect in Canada, South Africa, and the Caribbean. The United Kingdom used its most valuable instrument, the Royal Navy, to enforce the ban on the slave trade. Between 1807 and 1860, the West Africa Squadron intercepted around 1,600 slave ships and liberated over 150,000 Africans from the grim fate of slavery.The capture of the slaver 'Formidable' by HMS 'Buzzard', 17 December 1834.

The Gateway to Conquering Canada: The Siege of Louisbourg (1758) 🧵 Image Historical Background
The Seven Years’ War is regarded by some historians as the first true world war. Although the intensity and bloodshed of the 20th-century conflicts could not be matched by any war of the 18th century, geographically speaking, this claim is not far from the truth. While many countries fielded vast armies against each other all over Europe, British and French colonial forces incessantly fought in the Americas and the Indian subcontinent.Source: Wikipedia (user: Pinpin)

Leander-class light cruisers 🧵 HMNZS Achilles. Source: Torpedo Bay Navy Museum The Leander-class was a group of eight light cruisers built for the Royal Navy during the 1930s, which saw extensive service during the Second World War. They were constructed in two groups: five of the Leander group, which were destined for the Royal Navy, and a further three of the Amphion group which were later transferred to the Royal Australian Navy. Two units, the Achilles and Leander, would later join the New Zealand Division of the Royal Navy, making New Zealand a 2-cruiser station, a number the island would maintain until the 60s.

The Battle of the Saintes (1782): The Largest Naval Engagement of the 18th Century 🧵 Image Between April 9 and 12, 1782, over the course of four days, the Royal Navy achieved its greatest victory against the French during the American War of Independence, when Admiral Sir George Rodney defeated a French fleet of over 30 French ships of the line under Comte de Grasse. He successfully thwarted the planned invasion of Jamaica and restored British naval dominance in the West Indies. The French momentum was broken, and the British could now open peace negotiations from a position of power. This final engagement of the American Revolution is also considered by some to be the first instance of the use of the battle tactic of ‘breaking the line.’Battle of the Saintes, April 1782 by Nicholas Pocock

Using the Toilet Aboard a Ship of the Line: How Did They Do It?
Read More 👇🧵 Source: Facebook (user: SailorBert) Some 800 men lived and worked aboard a first-rate ship of the line, such as HMS Victory. These ships needed to be kept in good condition at all times.
