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
