On arriving at the gateway,[4] Pontiac and his warriors were freely admitted, but found the garrison under arms, the cannons loaded for service and the inhabitants ready for battle. At a glance he foresaw the certain failure of his scheme, and after being warned by Gladwin that his plot had been discovered, he retired still protesting friendship. Within a day or two afterwards he threw off all attempts at concealment, summoned his warriors, massacred several persons on the island now known as Belle Isle and commenced a siege which lasted for five weary months. During the siege, the garrison was relieved several times by provisions and ammunition from Niagara, and on July 29th, by the arrival of 280 soldiers commanded by Captain Dalyell together with 20 rangers from New Hampshire under Major Robert Rogers. Captain Dalyell now determined to "turn the tables" by an attack on the Indians. Gladwin opposed the idea, but was compelled to yield, and on July 31st 250 troops in three detachments marched against the savages. Pontiac in some way was informed of the plan and, ambushed on the border of Parents' Creek, afterwards called Bloody Run, awaited the approach of the soldiers. As the latter reached a small bridge that then crossed the stream not far from what is now the corner of Jefferson Avenue and Adair Street, they heard the war-whoop of the Indians and from every side bullets thinned their ranks. Dalyell and seventeen others were killed, nearly forty soldiers wounded and several captured. Within six hours after this ignominious failure, the rest were glad to be within the shelter of the stockade. The siege was then renewed with increased vigor until at last General Gage of Boston determined to send a force large enough to subdue the Indians. Accordingly, Colonel Bradstreet was put in command of a combined force of 100 friendly Indians, 900 Canadians, and a detachment of 219 Connecticut militia in charge of the noted Israel Putnam. They came by water from Albany and reached Detroit on August 26, 1764. Their bateaux and barges blocked the river; the display of flags and force alarmed the Indians, and made them yield before an army such as they had never seen before. Meantime the war-clouds of the Revolution were gathering. The common impression is that the war was fought in the East, around Boston and New York. The important events that occurred at Detroit are usually ignored; that, too, in spite of the fact that at no other point was so much use made of the Indians by the English.
