⚓ In spring 1805, Nelson set off after a French fleet that had escaped from Toulon — and before he could cross the Atlantic, he had to stop off the coast of Morocco and fill his casks. Water, not food, set the limit on how far and how long a sailing fleet could go.

This video follows the water through the ship. Why beer was the official drink, how a seventy-four used nearly three tons of water a day, and why a ship could carry food for far longer than she could carry anything to drink. Then the casks: leaguers, butts, puncheons and hogsheads, the ground tier bedded in shingle, and the emptied casks refilled with seawater to keep the ship stiff.

Inside the cask the water went green and foul — and then, strangely, sweetened again. We follow the watering parties ashore, Nelson’s anchorage in Sardinia, the water transports that kept the Brest blockade supplied at sea, and the iron tanks and distillers that finally stopped the water clock.

📜 What is known and what is reconstruction Cask counts, the Minerva’s cargo, the Deptford cask figures and the iron tank contracts come from the published research listed below. There was no single fixed water ration: the “gallon a day” figure is the rough planning allowance used for drinking and cooking together, and daily consumption is calculated from it. All images are AI-generated reconstructions: ships, holds, people and places are illustrative, not photographs or copies of specific historical artworks.
