The Torrey Canyon: The Day the Sea Turned Black

On the morning of March 18th, 1967, the supertanker Torrey Canyon struck Pollard's Rock on the Seven Stones reef between Land's End and the Isles of Scilly. She was carrying 119,000 tons of crude oil — the largest cargo ever to be wrecked on the British coast.

What followed was an environmental catastrophe and a governmental panic. Oil poured from the stricken ship's ruptured tanks at a rate of 6,000 tons per day. A slick 35 miles long spread across the sea toward the Cornish coast.

Salvage attempts failed. Pumping failed. Finally, the Royal Air Force was called in. For two days, RAF bombers dropped 62,000 gallons of napalm and aviation fuel on the wreck, attempting to burn off the oil. The Torrey Canyon blazed like a Viking funeral pyre.

But the oil kept coming. Beaches from Sennen to St Ives were covered in thick black crude. Seabirds died in their thousands — estimates suggest 15,000 birds perished. The British government, in desperation, sprayed 10,000 tons of detergent on the beaches, which proved more toxic than the oil itself.

The Torrey Canyon disaster was a wake-up call. It led directly to the creation of international maritime safety protocols, new tanker design requirements, and the birth of the modern environmental movement. The oil industry was forced to take responsibility for the damage it could cause.

Today, the Seven Stones lightship warns ships away from the reef. The Torrey Canyon's anchor sits in a garden in Sennen Cove — a memorial to the day the sea turned black.
