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
