The successful and rapid conquest of the Creeks opened the way for Jackson's Southern campaign against the English. As major-general he was sent to conclude a treaty with the Indians, which he soon arranged, and was then put in command of the Southern Division of the army, with headquarters at Mobile. The English made the neutral Spanish territory of Florida a basis of operations along the shores of the Gulf of Mexico, thus putting in peril both Mobile and New Orleans. They virtually possessed Pensacola, the Spanish force being too feeble to hold it, and made it the rendezvous of their fleets. The Spanish authorities made a show, indeed, of friendship with the United States, but the English flag floated over the forts of the city, and the governor was in sympathy with England. Such was the state of affairs when Jackson arrived at Mobile at the head of parts of three regiments of regulars, with a thousand miles of coast to defend, and without a fort adequately armed or garrisoned. He applied to the Secretary of War for permission to take Pensacola; but the government hesitated to attack a friendly power without further knowledge of their unfriendly acts, and the delayed response, ordering caution and waiting, did not reach him. Thrown upon his own resources, asking for orders and getting none, he was obliged to act without instructions, in face of vastly superior forces. And for this he can scarcely be blamed, since his situation demanded vigorous and rapid measures, before they could be indorsed by the Secretary of War. Pensacola, at the end of a beautiful bay, ten miles from the sea, with a fine harbor, was defended by Fort Barrancas, six miles from the town. Before it lay eight English men-of-war at anchor, the source of military supplies for the fort, on which floated the flags of both England and Spain. The fleet was in command of Captain Lord Percy, whose flagship was the "Hermes," while Colonel Nichols commanded the troops. This latter boastful and imprudent officer was foolish enough to issue a proclamation to the inhabitants of Louisiana and Kentucky to take up arms against their country. A body of Indians were also drilled in the service of the British, so far as Indians can be drilled to regular warfare. As soon as the true intentions of the English were known to General Jackson, who had made up his mind to take possession of Pensacola, he wrote to the Spanish governor,--a pompous, inefficient old grandee,--and demanded the surrender of certain hostile Creek chieftains, who had taken refuge in the town.
