It was a strange and difficult position in which Perry now found himself. The enemy with his squadron of five vessels controlled the lake. The building-yard at Erie was without protection. There were no guns, not even muskets or cartridges, and if there had been, there were no men to use them. Of the ship-carpenters who were sent on with their tools from Philadelphia only a few had come. All the supplies,--guns, sail-cloth, cordage, ammunition,--everything, in short, but timber, was to be brought a distance of five hundred miles over bad roads, through a country that was almost a wilderness. Finally, the little brig "Caledonia" and the four gunboats which together made up the whole of the squadron afloat were at Black Rock in the Niagara River, and were unable to make their way past the enemy's river batteries into the lake. Perry began his work at once. He sent to Buffalo for seamen, and at his request some companies of militia were posted at Erie. He went himself to Pittsburg, where he procured small cannon and muskets to assist in the defence. Iron was bought at Buffalo, and when this supply was exhausted, every scrap that could be got in the neighborhood was worked up for use in the construction of the fleet. Blacksmiths were found among the militia. To obtain the timber for the vessels, trees were felled and sawn up, and all was so quickly done that it often happened that wood which at daybreak had been growing in the forest was before nightfall nailed in place upon the ship. With such extraordinary despatch did the young commodore push forward his work, that by the third week in May all the vessels had been launched from the ways and were afloat in the harbor of Erie.
