After the fall of Fort George, the English abandoned the whole Niagara frontier, and there was therefore at last some slight chance that the vessels at Black Rock might be enabled to make their way into Lake Erie. Leaving the Ontario fleet, Perry repaired to Black Rock, and with the help of oxen and two hundred soldiers the five boats were tracked up against the rapid current of the Niagara. A fortnight was consumed before they reached the head of the river, after laborious exertions, and "a fatigue," said Perry, "almost incredible." At last they were out upon Lake Erie, but before them there was still the difficult task of eluding the British squadron, whose flagship, the "Queen Charlotte," was alone a match for all of them, and which had besides four smaller vessels. The enemy was in the neighborhood, and the winds were contrary; but Perry with great skill managed to pass them unopposed, and at last brought his vessels into the harbor of Erie, thus joining in one squadron all his forces.

It was now the end of June, and for a month Perry was engaged in fitting out the vessels that had been launched in May, and in preparing their crews. One of the brigs was named the "Lawrence," in honor of the captain of the "Chesapeake," who had just before died of his wounds in the action with the "Shannon;" the other was called the "Niagara." The seamen, who were mostly drawn from the Lake Ontario squadron, came in slowly. As soon as one detachment arrived, the men were placed on board and stationed, and every day when it was possible to do it they were exercised at the guns. But the hardest task was yet to come. Upon the bar at the mouth of the harbor the water was only six feet deep, and outside lay the British squadron on the watch. To get the two brigs over the bar under the enemy's fire seemed hopeless, and Commodore Barclay, the British commander, well knew his advantage. But one day early in August, either because he thought the ships were not ready, or because he fancied that he could overcome the Americans in any case, he left his post of observation and took his squadron over to the Canadian shore.

The American commodore, as he was now called, saw his opportunity and made the most of it. Five of the small vessels were sent across the bar, where they were cleared for action. The "Niagara," anchoring close inside, pointed her guns down the channel; and the "Lawrence" was towed down to be taken across. Every means was used to lighten her; her guns were hoisted out, and when all was ready, two great scows were fitted alongside, and filled with water so that they sunk to the edge. Huge cross-timbers were then run through the ports of the brig, their ends resting upon blocks of wood placed in the sunken scows. The scows were now pumped out, and as they came up they lifted the brig with them. It was anxious work, for the enemy might return at any moment, and finding the "Lawrence" defenceless and immovable, might riddle her until she could not float. The first trial failed, for there was little water on the bar and the brig could not be lifted high enough to get her over. But the men worked with might and main, the militia helping the blue-jackets; and the scows were readjusted, so that at last the ship had forced her way over the sands and passed into the deep water beyond. Here she was joined by the "Niagara."

The fleet of Commodore Barclay now came in sight, and although it was a little late, a smart attack might yet have saved it the supremacy which it had held thus far. The guns were still to be put on board the "Lawrence;" and to gain time Perry ordered two schooners, the "Ariel" and "Scorpion," to stand out toward Barclay's vessels and annoy them with their guns. The schooners advanced so boldly that the enemy were fully occupied. In a short time the "Lawrence" had received her battery and placed it in position, and she was ready for action. The enemy's opportunity was lost, and Barclay sailed away to the northern shore. From this moment Perry had the advantage on Lake Erie.

The American fleet was now only waiting to complete its crews before seeking its adversary. Soon a final detachment of one hundred men came from Lake Ontario, brought by Lieutenant Elliott, who was placed in command of the "Niagara." The "Lawrence" was selected by Commodore Perry as his flagship. He had now through his energetic efforts a force superior to the enemy both in guns and men, and the next few days were spent in training the mixed crews, and in reconnoitring and manœuvering on the lake.

At sunrise on the morning of the 10th of September, as the American ships were lying at anchor at Put-in Bay, the British squadron was sighted from the mast-head of the "Lawrence," standing in for the bay. Lieutenant Forrest, the officer of the deck, reported the news to Commodore Perry, and immediately the signal was hoisted on the flagship. "Under way to get!" For a few moments all was hurry and bustle, and in a little while the American squadron was under sail, beating out of the harbor.

The breeze was light, and as the enemy had the weather-gage, several hours were now passed in manœuvering. But in the course of the forenoon the wind shifted, bringing the English fleet to leeward, upon which Perry determined to advance without further preliminaries. The enemy were now in line of battle, hove to, the schooner "Chippeway" leading. Next came the "Detroit," Commodore Barclay's flagship, with the brig "Hunter" astern. Next to the "Hunter" lay the "Queen Charlotte," the second of the enemy's large ships; and the schooners "Lady Prevost" and "Little Belt" brought up the rear.

The American squadron was so arranged as to bring its largest vessels opposite to the largest of the enemy. The commodore led in his flagship the "Lawrence," supported by the "Ariel" and "Scorpion" upon his weather-bow. He chose Barclay's flagship as his own antagonist. Following him was the brig "Caledonia," which was to engage the "Hunter." Next came the "Niagara," Elliott's vessel, to oppose the "Queen Charlotte;" and the line was completed by the schooners "Somers," "Porcupine," and "Tigress," and the sloop "Trippe," which would take care of the enemy's rear.

The English lay in compact order, broadside on, their red ensigns opening to the light breeze. No picture could be drawn more peaceful or more beautiful than that upon which the sun shone on this September morning as it lit up with sparkling brilliancy the rippling waters of the lake. The long column of the Americans came slowly down with all sails set, led by the "Lawrence," at whose mast-head was unfolded the lettered flag bearing the words, "Don't give up the ship,"—the last order of the ill-fated commander of the "Chesapeake." It was Perry's battle-flag; and as it was displayed and the words were read by the different crews, cheer upon cheer rang out, caught up from ship to ship down the long line of the advancing column. The last preparations had now been made; the shot were in the racks, the pistols and cutlasses arranged at hand, and the decks sanded to give a foothold, when in a few moments they would become slippery with blood. All was in readiness, and the men only waited to join battle.
