The settlement was widely scattered, extending along the east shore of the Detroit river for about eight miles from Lake St Clair, and along the west shore for about six miles, four above and two below the fort. On either side of the river the fertile fields and the long row of whitewashed, low-built houses, with their gardens and orchards of apple and pear trees, fenced about with rounded pickets, presented a picture of peace and plenty. The summers of the inhabitants were enlivened by the visits of the Indians and the traders; and in winter they light-heartedly whiled away the tedious hours with gossip and dance and feast, like the habitants along the Richelieu and the St Lawrence.

The militia of the settlement, as we have seen, had been deprived of their arms at the taking over of Detroit by Robert Rogers; and for the most part the settlers maintained a stolid attitude towards their conquerors, from whom they suffered no hardship and whose rule was not galling. The British had nothing to fear from them. But the Indians were a force to be reckoned with. There were three Indian villages in the vicinity—the Wyandot, on the east side of the river, opposite the fort; the Ottawa, five miles above, opposite Ile au Cochon (Belle Isle); and the Potawatomi about two miles below the fort on the west shore. The Ottawas here could muster 200 warriors, the Potawatomis about 150, and the Wyandots 250, while near at hand were the Chippewas, 320 strong. Pontiac, although head chief of the Ottawas, did not live in the village, but had his wigwam on Ile a la Peche, at the outlet of Lake St Clair, a spot where whitefish abounded. Here he dwelt with his squaws and papooses, not in 'grandeur,' but in squalid savagery. Between the Indians and the French there existed a most friendly relationship; many of the habitants, indeed, having Indian wives.

Near the centre of the settlement, on the west bank of the river, about twenty miles from Lake Erie, stood Fort Detroit, a miniature town. It was in the form of a parallelogram and was surrounded by a palisade twenty-five feet high. According to a letter of an officer, the walls had an extent of over one thousand paces. At each corner was a bastion and over each gate a blockhouse. Within the walls were about one hundred houses, the little Catholic church of Ste Anne's, a council-house, officers' quarters, and a range of barracks. Save for one or two exceptions the buildings were of wood, thatched with bark or straw, and stood close together. The streets were exceedingly narrow; but immediately within the palisade a wide road extended round the entire village. The spiritual welfare of the French and Indian Catholics in the garrison was looked after by Father Potier, a Jesuit, whose mission was in the Wyandot village, and by Father Bocquet, a Recollet, who lived within the fort; Major Henry Gladwyn was in command. He had a hundred and twenty soldiers, and two armed schooners, the Gladwyn and the Beaver, were in the river near by.

On the first day of May 1763, Pontiac came to the main gate of the fort asking to be allowed to enter, as he and the warriors with him, forty in all, desired to show their love for the British by dancing the calumet or peace dance. Gladwyn had not the slightest suspicion of evil intent, and readily admitted them. The savages selected a spot in front of the officers' houses; and thirty of them went through their grotesque movements, shouting and dancing to the music of the Indian drum, and all the while waving their calumets in token of friendship. While the dancers were thus engaged, the remaining ten of the party were busily employed in surveying the fort—noting the number of men and the strength of the palisades. The dance lasted about an hour. Presents were then distributed to the Indians, and all took their departure.

Pontiac now summoned the Indians about Detroit to another council. On this occasion the chiefs and warriors assembled in the council-house in the Potawatomi village south of the fort. When all were gathered together Pontiac rose and, as at the council at the river Ecorces, in a torrent of words and with vehement gestures, denounced the British. He declared that under the new occupancy of the forts in the Indian country the red men were neglected and their wants were no longer supplied as they had been in the days of the French; that exorbitant prices were charged by the traders for goods; that when the Indians were departing for their winter camps to hunt for furs they were no longer able to obtain ammunition and clothing on credit; and, finally, that the British desired the death of the Indians, and it was therefore necessary as an act of self-preservation to destroy them. He once more displayed the war-belt that he pretended to have received from the king of France. This belt told him to strike in his own interest and in the interest of the French. He closed his speech by saying that he had sent belts to the Chippewas of Saginaw and the Ottawas of Michilimackinac and of the river La Tranche (the Thames). Seeing that his words were greeted with grunts and shouts of approval and that the assembled warriors were with him to a man, Pontiac revealed a plan he had formed to seize the fort and slaughter the garrison. He and some fifty chiefs and warriors would wait on Gladwyn on the pretence of discussing matters of importance. Each one would carry beneath his blanket a gun, with the barrel cut short to permit of concealment. Warriors and even women were to enter the fort as if on a friendly visit and take up positions of advantage in the streets, in readiness to strike with tomahawks, knives, and guns, all which they were to have concealed beneath their blankets. At the council Pontiac was to address Gladwyn and, in pretended friendship, hand him a wampum belt. If it were wise to strike, he would on presenting the belt hold its reverse side towards Gladwyn. This was to be the signal for attack. Instantly blankets were to be thrown aside and the officers were to be shot down. At the sound of firing in the council-room the Indians in the streets were to fall on the garrison and every British soldier was to be slain, care being taken that no Frenchman suffered. The plan, by its treachery, and by its possibilities of slaughter and plunder, appealed to the savages; and they dispersed to make preparations for the morning of the 7th, the day chosen for carrying out the murderous scheme.

The plot was difficult to conceal. The aid of French blacksmiths had to be sought to shorten the guns. Moreover, the British garrison had some friends among the Indians. Scarcely had the plot been matured when it was discussed among the French, and on the day before the intended massacre it was revealed to Gladwyn. His informant is not certainly known. A Chippewa maiden, an old squaw, several Frenchmen, and an Ottawa named Mahiganne have been mentioned. It is possible that Gladwyn had it from a number of sources, but most likely from Mahiganne. The 'Pontiac Manuscript,' probably the work of Robert Navarre, the keeper of the notarial records of the settlement, distinctly states that Mahiganne revealed the details of the plot with the request that Gladwyn should not divulge his name; for, should Pontiac learn, the informer would surely be put to death. This would account for the fact that Gladwyn, even in his report of the affair to Amherst, gives no hint as to the person who told him.

Gladwyn at once made preparations to receive Pontiac and his chiefs. On the night of the 6th instructions were given to the soldiers and the traders within the fort to make preparations to resist an attack, and the guards were doubled. As the sentries peered out into the darkness occasional yells and whoops and the beating of drums reached their ears, telling of the war-dance that was being performed in the Indian villages to hearten the warriors for the slaughter.

Gladwyn determined to act boldly. On the morning of the 7th all the traders' stores were closed and every man capable of bearing weapons was under arms; but the gates were left open as usual, and shortly after daylight Indians and squaws by twos and threes began to gather in the fort as if to trade. At ten in the morning a line of chiefs with Pontiac at their head filed along the road leading to the river gate. All were painted and plumed and each one was wrapped in a brightly coloured blanket. When they entered the fort they were astonished to see the warlike preparations, but stoically concealed their surprise. Arrived in the council-chamber, the chiefs noticed the sentinels standing at arms, the commandant and his officers seated, their faces stern and set, pistols in their belts and swords by their sides. So perturbed were the chiefs by all this warlike display that it was some time before they would take their seats on the mats prepared for them. At length they recovered their composure, and Pontiac broke the silence by asking why so many of the young men were standing in the streets with their guns. Answer was made through the interpreter La Butte that it was for exercise and discipline. Pontiac then addressed Gladwyn, vehemently protesting friendship. All the time he was speaking Gladwyn bent on him a scrutinizing gaze, and as the chief was about to present the wampum belt, a signal was given and the drums crashed out a charge. Every doubt was removed from Pontiac's mind—his plot was discovered. His nervous hand lowered the belt; but he recovered himself immediately and presented it in the ordinary way. Gladwyn replied to his speech sternly, but kindly, saying that he would have the protection and friendship of the British so long as he merited it. A few presents were then distributed among the Indians, and the council ended. The chiefs, with their blankets still tightly wrapped about them, filed out of the council-room and scattered to their villages, followed by the disappointed rabble of fully three hundred Indians, who had assembled in the fort.

On the morrow, Pontiac, accompanied by three chiefs, again appeared at the fort, bringing with him a pipe of peace. When this had been smoked by the officers and chiefs, he presented it to Captain Campbell, as a further mark of friendship. The next day he was once more at the gates seeking entrance. But he found them closed: Gladwyn felt that the time had come to take no chances. This morning a rabble of Potawatomis, Ottawas, Wyandots, and Chippewas thronged the common just out of musket range. On Pontiac's request for a conference with Gladwyn he was sternly told that he might enter alone. The answer angered him, and he strode back to his followers. Now, with yells and war-whoops, parties of the savages bounded away on a murderous mission. Half a mile behind the fort an English woman, Mrs Turnbull, and her two sons cultivated a small farm. All three were straightway slain. A party of Ottawas leapt into their canoes and paddled swiftly to Ile au Cochon, where lived a former sergeant, James Fisher. Fisher was seized, killed, and scalped, his young wife brutally murdered, and their two little children carried into captivity. On this same day news was brought to the fort that Sir Robert Davers and Captain Robertson had been murdered three days before on Lake St Clair by, Chippewas who were on their way from Saginaw to join Pontiac's forces. Thus began the Pontiac War in the vicinity of Detroit. For several months the garrison was to know little rest.

That night at the Ottawa village arose the hideous din of the war-dance, and while the warriors worked themselves into a frenzy the squaws were busy breaking camp. Before daylight the village was moved to the opposite side of the river, and the wigwams were pitched near the mouth of Parent's Creek, about a mile and a half above the fort. On the morning of the 10th the siege began in earnest. Shortly after daybreak the yells of a horde of savages could be heard north and south and west. But few of the enemy could be seen, as they had excellent shelter behind barns, outhouses, and fences. For six hours they kept up a continuous fire on the garrison, but wounded only five men. The fort vigorously returned the fire, and none of the enemy dared attempt to rush the palisades. A cluster of buildings in the rear sheltered a particularly ferocious set of savages. A three-pounder—the only effective artillery in the fort—was trained on this position; spikes were bound together with wire, heated red-hot, and fired at the buildings. These were soon a mass of flames, and the savages concealed behind them fled for their lives.
