In 1759, Thomas Slade sat in a Chatham dockyard drawing the lines of a ship that wouldn't fire her most famous broadside for another 46 years.
Nelson was still a year from being born.
Slade's design was a quiet piece of genius. A 3,500-ton first-rate that could make 11 knots in the right conditions, combining the firepower of a floating fortress with speed few ships her size could match.
The scale of what he was asking for is almost hard to picture. Over 6,000 trees, mostly oak from Kent, the New Forest, and Germany. Millions of individual pieces of timber. 26 miles of rope. 768 pulley blocks. 37 sails covering four acres of canvas, with Dundee weavers spending roughly 1,200 hours on the topsail alone.
She took six years to build. Launched in 1765 to a band playing Rule Britannia, then promptly sat in reserve for 13 years.
By 1799 she was rotting at Chatham, holding French and Spanish prisoners. She was 34 years old, structurally weakened, and the Admiralty had already discussed breaking her up for timber.
What saved her was an accident. On 8 October 1799, HMS Impregnable ran aground off Portsmouth. The Navy was suddenly short a three-decked first-rate, and the old ship in Chatham got a reprieve.
The refit cost ÂŁ70,933, three times the estimate. New copper hull lining, new gun ports, her 42-pounders swapped for faster 32-pounders. She came out of dockyard in 1803, and Nelson hoisted his flag the same year.
At Trafalgar she carried 104 guns. Her broadside weighed over 1,100 pounds of iron, more than every gun in Wellington's artillery at Waterloo combined. Her gunlocks let British crews fire three broadsides to the enemy's two.
The approach to the Franco-Spanish line took 40 minutes under fire before she could reply. When she finally broke through between Bucentaure and Redoubtable, her first broadside killed or wounded between 300 and 450 of Bucentaure's crew in a single pass. A carronade sent a keg of 500 musket balls through a French gunport.
At 1:15pm Nelson was shot through the shoulder. He died at 4:30pm, after being told the battle was won.
Victory lost 57 killed and 102 wounded. The enemy lost 18 ships, over 4,400 dead, and more than 2,500 wounded. She took over 90 cannonballs, lost her wheel mid-battle (40 men rigged emergency steering below decks), was towed to Gibraltar, and sailed home in November carrying Nelson's body in a cask of brandy.
Slade died in 1771. He never saw her fight.
His ship still sits in Portsmouth dry dock today, the oldest warship in the world still in naval service, flagship of the First Sea Lord. Twenty percent of her timber is original.
The keel he drew is still there.
