After the signing of the Treaty of Amiens, Bonaparte sent out a squadron
commanded by Rear-Admiral Linois, conveying General Charles Decaen, who
was commissioned to administer the former French possessions in India,
which, under the terms of the treaty, were to be surrendered to France.
But when the expedition arrived at Pondicherry, the Governor-General of
India, Lord Wellesley, gave orders to his subordinates that no
concessions were to be made to the French without his express authority;
and as he stubbornly refused to give his warrant for surrendering an inch
of territory, there was nothing for General Decaen to do but sail away to
Mauritius, then, as already remarked, a French colony. Lord Wellesley
acted under secret orders from the Secretary of State, Lord Hobart, dated
October 17, 1802, only seven months after the treaty was signed, for the
British Government did not believe in the permanency of the peace and did
not desire the French to re-assert a footing in India, where their
presence, in the event of a renewal of hostilities, would be dangerous.

When the war was renewed, Linois, with his squadron, was still in the
Indian Ocean. The Isle of France was not a self-supporting colony, but
had to depend on money and supplies obtained either from Europe or from
the vessels of the East India Company, which, from time to time, were
captured by French privateers and men-of-war. When Nelson shattered the
naval power of France at Trafalgar in 1805, and vigilant British frigates
patrolled the whole highway of commerce from Europe to the Cape of Good
Hope, Decaen's position became precarious. The supplies sent out to him
were frequently captured by the enemy; and had it not been that Port
Louis became a regular nest of adventurous French privateers--"pirates,"
the British called them--who frequently found a rich prey in the shape of
heavily laden India merchantmen, his garrison must soon have been starved
out.
