Sir James Yeo being still very anxious about the naval stores which the enemy were so industriously collecting at Sackett's Harbour, determined to try if possession of at least a part of them could not be obtained. Accordingly, he blockaded Sackett's Harbour, and on the morning of the 29th of May, a boat belonging to the enemy, laden with a cable large enough for a ship of war, and with two twenty-four pounders, forming one of a flotilla of sixteen boats from Oswego, containing naval and military stores, was intercepted and captured. Captains Popham and Spilsbury, having with them two gun-boats and five barges, were immediately sent in search of the other boats. They soon learned where the missing boats were. Fearing capture, the Americans had taken shelter in Sandy Creek. It was resolved to root them out, if possible, and accordingly the British gun-boats and barges entered the Creek. Captains Popham and Spilsbury immediately looked about them, and found the enterprise to be rather hazardous. The creek was narrow and winding. An attack was, nevertheless, determined upon. For about half a mile the assailants proceeded cautiously up the creek, when, as they turned its elbow, the enemy's boats were in full view. The troops immediately landed on both banks and were advancing when the sixty-eight pounder carronade in the foremost boat was disabled, and it was necessary to bring the twenty-four pounder in the stern of the boat to bear upon the enemy. But no sooner had an effort been made to get the boat round than the enemy took it into their heads that the attacking party designed to make off, and advancing hastily in considerable numbers, rifles, militia, cavalry, regular infantry, and Indians, the British, unable to retreat, were overpowered, the captured being with difficulty rescued by their humane American enemies, from the tomahawks and scalping knives of the Indians. On Lake Champlain an attempt was made on the 14th of May, to capture or destroy two new American vessels building at Vergennes, by Captain Pring, of the Royal Navy, but finding the enemy prepared to receive him more warmly than courteously, Captain Pring desisted and returned to Isle-aux-Noix.
