But fortune or Providence protected the schooners, the blazing raft passed within a hundred feet of them, and floating harmlessly down the stream, consumed nothing but itself. This attempt was several times repeated, but Gladwyn, on his part, provided boats and floating logs, which were moored by chains at some distance above the vessels, and foiled every attempt.

In the meantime, unknown to the garrison, Captain Dalyell was on his way to Detroit with twenty-two barges, bearing two hundred and eighty men, with several small cannon, and a fresh supply of provisions and ammunition. Under cover of night and fog they reached the fort in safety, but not until they sustained an attack from the Indians which resulted in the loss of fifteen men. With this expedition was Major Rogers, commander of the famous Rogers's Rangers, and twenty of his men.

Captain Dalyell had a conference with Gladwyn, and requested permission to march out on the following night and attack the Indian camp. The commander, better acquainted with the position of affairs, opposed it; but Dalyell urged the matter so strongly, Gladwyn gave a reluctant consent. About two o'clock on the morning of July 31, the gates were silently opened, and two hundred and fifty men marched up the road along the river's shore. In the river, keeping abreast of the troops, two bateaux, each carrying a swivel gun, were rowed with muffled oars. As there was no moon shining, everything seemed favorable to strike a deadly blow at the camp of Pontiac. But though they knew it not, that vigilant and crafty chieftain was apprised of this movement by his spies, and with several hundred Indians lay in ambush at the bridge across Parent's creek, a mile and a half from the fort. As the English drew near the dangerous pass they could discern the house of Meloche, mentioned before, upon a rising ground to the left, while in front the bridge was dimly visible, and the ridges beyond it seemed like a wall of blackness, partly due to the fog rising from the river. The advance guard were half way over the bridge and the main body just entering upon it. Suddenly there was a wild war-whoop in the darkness, and the ridges, fences, trees and anything which could afford shelter to a savage, burst into flame. Half the advance guard fell at the first discharge; the terrified survivors fled to the rear, and in a moment the whole column was thrown into confusion. Dalyell rushed to the front and did what he could to rally his men. His clarion voice rang out above this infernal din. But all in vain. He received several wounds, and was in the act of rescuing a disabled soldier when he was killed. It is said that Pontiac ordered the head of the gallant captain to be cut off and set upon a post. The total command was demoralized by his fall. In this crisis Major Rogers and his twenty rangers, followed by a number of the regulars, took possession of a strong house, which commanded the road, owned by a Canadian named Campau. Barricading the windows, they held the savages at bay and covered the retreat. Captain Grant hurried forward and took another strong position near the river. From here he ordered the two armed bateaux to return to a point opposite Campau's house, and open a fire of swivels in order to scatter the Indians and rescue Rogers and his men. This was promptly done, and the gallant Rogers and his handful of rangers, who, by their courage, saved the command from total destruction, were in turn rescued, just as the savage horde was about to overpower them by sheer force of numbers. The rangers made their way to the fort under cover of the cannonade.

The fight at Bloody Run, as Parent's creek has since been called, cost the garrison at Detroit fifty-nine men killed and wounded, according to Parkman, while Thatcher, strange to say, estimates the loss of the English at seventy men killed and forty wounded. This was the last important event attending the prosecution of the siege.

Not long after this, the schooner Gladwyn, having been sent down to Niagara with letters and dispatches, made the trip in safety. She was now returning, having on board Horst, her master; Jacobs, her mate, and a crew of ten men, besides six Iroquois Indians, supposed to be friendly to the English. She entered the Detroit river on the night of September 3, and in the morning the six Indians asked to be put ashore, and the request was foolishly granted.

That they went at once to Pontiac with a report of the weakness of the crew there can be no doubt. Certain it is, the wind failing, the schooner anchored about nine miles below the fort. Here she was attacked by three hundred and fifty Indians, at night. The savages swarmed over the sides of the vessel by scores, but they were met with such desperate courage and furious resistance that in a few minutes the English had killed and wounded more than twice their own number. There were only twelve men on board and they killed and wounded twenty-seven Indians; of the wounded, eight died in a few days. But resistance was useless. Ten or fifteen Indians surrounded each gallant defender. Just as all seemed over, Jacobs, the mate, shouted, "Fire the magazine, boys, and blow her up!" This desperate command saved her and her crew. Some Wyandots understood the meaning of the words, and gave the alarm to their companions. With a wild cry of terror the Indians leaped from the vessel into the water, and all were seen swimming and diving in all directions, to escape the explosion. The savages did not renew the attack.

The next morning the Gladwyn sailed up the river, reaching the fort safely. Six of her crew escaped unhurt; of the other six, two, including Horst, the master, were killed and four seriously wounded, while the Indians had seven men killed outright, and about twenty wounded, of whom eight were known to have died within a few days. The whole action lasted but a few minutes, but the fierceness of the struggle is apparent from the loss on both sides. The survivors of the little crew each received a medal.

The news of the disaster at Bloody Run, following on the heels of the ill-fated Cuyler's expedition, was conveyed to Niagara by the schooner Gladwyn on the last voyage, just recorded.

These disasters at the siege of Detroit, together with the fact that nine out of the twelve forts on the frontier had been captured by Pontiac's warriors, forced Sir Jeffrey Amherst to the reluctant conclusion that the tribes had risen in a general insurrection. As commander-in-chief of these English forces, he saw the time had come for decisive action with a large force if he would regain what was lost, and force the Indians into subjection.
