Presently the Indians grew tired of this useless warfare and withdrew to their villages. Gladwyn, thinking that he might bring Pontiac to terms, sent La Butte to ask the cause of the attack and to say that the British were ready to redress any wrongs from which the Indians might be suffering. La Butte was accompanied by Jean Baptiste Chapoton, a captain of the militia and a man of some importance in the fort, and Jacques Godfroy, a trader and likewise an officer of militia. It may be noted that Godfroy's wife was the daughter of a Miami chief. The ambassadors were received in a friendly manner by Pontiac, who seemed ready to cease hostilities. La Butte returned to the fort with some of the chiefs to report progress; but when he went again to Pontiac he found that the Ottawa chief had made no definite promise. It seems probable, judging from their later actions, that Chapoton and Godfroy had betrayed Gladwyn and urged Pontiac to force the British out of the country. Pontiac now requested that Captain Donald Campbell, who had been in charge of Detroit before Gladwyn took over the command, should come to his village to discuss terms. Campbell was confident that he could pacify the Indians, and, accompanied by Lieutenant George McDougall, he set out along the river road for the Ottawas' encampment at Parent's Creek. As the two officers crossed the bridge at the mouth of the creek, they were met by a savage crowd—men, women, and children—armed with sticks and clubs. The mob rushed at them with yells and threatening gestures, and were about to fall on the officers when Pontiac appeared and restored order. A council was held, but as Campbell could get no satisfaction he suggested returning to the fort. Thereupon Pontiac remarked: 'My father will sleep to-night in the lodges of his red children.' Campbell and McDougall were given good quarters in the house of Jean Baptiste Meloche. For nearly two months they were to be kept close prisoners.

So far only part of the Wyandots had joined Pontiac: Father Potier had been trying to keep his flock neutral. But on the 11th Pontiac crossed to the Wyandot village, and threatened it with destruction if the warriors did not take up the tomahawk. On this compulsion they consented, no doubt glad of an excuse to be rid of the discipline of their priest.

Another attack on the fort was made, this time by about six hundred Indians; but it was as futile as the one of the earlier day. Pontiac now tried negotiation. He summoned Gladwyn to surrender, promising that the British should be allowed to depart unmolested on their vessels. The officers, knowing that their communications with the east were cut, that food was scarce, that a vigorous assault could not fail to carry the fort, urged Gladwyn to accept the offer, but he sternly refused. He would not abandon Detroit while one pound of food and one pound of powder were left in the fort. Moreover, the treacherous conduct of Pontiac convinced him that the troops and traders as they left the fort would be plundered and slaughtered. He rejected Pontiac's demands, and advised him to disperse his people and save his ammunition for hunting.

At this critical moment Detroit was undoubtedly saved by a French Canadian. But for Jacques Baby, the grim spectre Starvation would have stalked through the little fortress. Baby was a prosperous trader and merchant who, with his wife Susanne Reaume, lived on the east shore of the river, almost opposite the fort. He had a farm of one thousand acres, two hundred of which were under cultivation. His trading establishment was a low-built log structure eighty feet long by twenty wide. He owned thirty slaves—twenty men and ten women. He seems to have treated them kindly; at any rate, they loyally did his will. Baby agreed to get provisions into the fort by stealth; and on a dark night, about a week after the siege commenced, Gladwyn had a lantern displayed on a plank fixed at the water's edge. Baby had six canoes in readiness; in each were stowed two quarters of beef, three hogs, and six bags of meal. All night long these canoes plied across the half-mile stretch of water and by daylight sufficient food to last the garrison for several weeks had been delivered.

From day to day the Indians kept up a desultory firing, while Gladwyn took precautions against a long siege. Food was taken from the houses of the inhabitants and placed in a common storehouse. Timber was torn from the walks and used in the construction of portable bastions, which were erected outside the fort. There being danger that the roofs of the houses would be ignited by means of fire-arrows, the French inhabitants of the fort were made to draw water and store it in vessels at convenient points. Houses, fences, and orchards in the neighbourhood were destroyed and levelled, so that skulking warriors could not find shelter. The front of the fort was comparatively safe from attack, for the schooners guarded the river gate, and the Indians had a wholesome dread of these floating fortresses.

About the middle of the month the Gladwyn sailed down the Detroit to meet a convoy that was expected with provisions and ammunition from Fort Schlosser. At the entrance to Lake Erie, as the vessel lay becalmed in the river, she was suddenly beset by a swarm of savages in canoes; and Pontiac's prisoner, Captain Campbell, appeared in the foremost canoe, the savages thinking that the British would not fire on them for fear of killing him. Happily, a breeze sprang up and the schooner escaped to the open lake. There was no sign of the convoy; and the Gladwyn sailed for the Niagara, to carry to the officers there tidings of the Indian rising in the west.

On May 30 the watchful sentries at Detroit saw a line of bateaux flying the British flag rounding a point on the east shore of the river. This was the expected convoy from Fort Schlosser, and the cannon boomed forth a welcome. But the rejoicings of the garrison were soon stilled. Instead of British cheers, wild war-whoops resounded from the bateaux. The Indians had captured the convoy and were forcing their captives to row. In the foremost boat were four soldiers and three savages. Nearing the fortress one of the soldiers conceived the daring plan of overpowering the Indian guard and escaping to the Beaver, which lay anchored in front of the fort. Seizing the nearest savage he attempted to throw him into the river; but the Indian succeeded in stabbing him, and both fell overboard and were drowned. The other savages, dreading capture, leapt out of the boat and swam ashore. The bateau with the three soldiers in it reached the Beaver, and the provisions and ammunition it contained were taken to the fort. The Indians in the remaining bateaux, warned by the fate of the leading vessel, landed on the east shore; and, marching their prisoners overland past the fort, they took them across the river to Pontiac's camp, where most of them were put to death with fiendish cruelty.

The soldiers who escaped to the Beaver told the story of the ill-fated convoy. On May 13 Lieutenant Abraham Cuyler, totally ignorant of the outbreak of hostilities at Detroit, had left Fort Schlosser with ninety-six men in ten bateaux. They had journeyed in leisurely fashion along the northern shore of Lake Erie, and by the 28th had reached Point Pelee, about thirty miles from the Detroit river. Here a landing was made, and while tents were being pitched a band of painted savages suddenly darted out of the forest and attacked a man and a boy who were gathering wood. The man escaped, but the boy was tomahawked and scalped. Cuyler drew up his men in front of the boats, and a sharp musketry fire followed between the Indians, who were sheltered by a thick wood, and the white men on the exposed shore. The raiders were Wyandots from Detroit, the most courageous and intelligent savages in the region. Seeing that Cuyler's men were panic-stricken, they broke from their cover, with unusual boldness for Indians, and made a mad charge. The soldiers, completely unnerved by the savage yells and hurtling tomahawks, threw down their arms and dashed in confusion to the boats. Five they succeeded in pushing off, and into these they tumbled without weapons of defence. Cuyler himself was left behind wounded; but he waded out, and was taken aboard under a brisk fire from the shore. The Indians then launched two of the abandoned boats, rushed in pursuit of the fleeing soldiers, speedily captured three of the boats, and brought them ashore in triumph. The two others, in one of which was Cuyler, hoisted sail and escaped. The Indians, as we have seen, brought the captured boats and their prisoners to Detroit. Cuyler had directed his course to Sandusky, but finding the blockhouse there burnt to the ground, he had rowed eastward to Presqu'isle, and then hastened to Niagara to report the disaster.

The siege of Detroit went on. Towards the middle of June, Jacques Baby brought word to the commandant that the Gladwyn was returning from the Niagara with supplies and men, and that the Indians were making preparations to capture her. A few miles below Detroit lay Fighting Island; between it and the east shore, Turkey Island. Here the savages had erected a breastwork, so carefully concealed that it would be difficult even for the keenest eyes to detect its presence. The vessel would have to pass within easy range of this barricade; and it was the plan of the Indians to dart out in their canoes as the schooner worked up-stream, seize her, and slay her crew. On learning this news Gladwyn ordered cannon to be fired to notify the captain that the fort still held out, and sent a messenger to meet the vessel with word of the plot. It happened that the Gladwyn was well manned and prepared for battle. On board was Cuyler with twenty-two survivors of the ill-starred convoy, besides twenty-eight men of Captain Hopkins's company. To deceive the Indians as to the number of men, all the crew and soldiers, save ten or twelve, were concealed in the hold; to invite attack, the vessel advanced boldly up-stream, and at nightfall cast anchor in the narrow channel in front of Turkey Island. About midnight the Indians stealthily boarded their canoes and cautiously, but confidently, swept towards her with muffled paddles. The Gladwyn was ready for them. Not a sound broke the silence of the night as the Indians approached the schooner; when suddenly the clang of a hammer against the mast echoed over the calm waters, the signal to the soldiers in the hold. The Indians were almost on their prey; but before they had time to utter the war-whoop, the soldiers had come up and had attacked the savages with bullets and cannon shot. Shrieks of death arose amid the din of the firing and the splash of swimmers hurriedly making for the shore from the sinking canoes. In a moment fourteen Indians were killed and as many more wounded. From behind the barricade the survivors began a harmless musketry fire against the schooner, which simply weighed anchor and drifted down-stream to safety. A day or two later she cleared Turkey Island and reached the fort, pouring a shattering broadside into the Wyandot village as she passed it. Besides the troops, the Gladwyn had on board a precious cargo of a hundred and fifty barrels of provisions and some ammunition. She had not run the blockade unscathed, for in passing Turkey Island one sergeant and four men had been wounded. There was rejoicing in the fort when the reinforcement marched in. This additional strength in men and provisions, it was expected, would enable the garrison to hold out for at least another month, within which time soldiers would arrive in sufficient force to drive the Indians away.

In the meantime Pontiac was becoming alarmed. He had expected an easy victory, and was not prepared for a protracted siege. He had drawn on the French settlers for supplies; his warriors had slain cattle and taken provisions without the consent of the owners. Leaders in the settlement now waited on Pontiac, making complaint. He professed to be fighting for French rule, and expressed sorrow at the action of his young men, promising that in future the French should be paid. Acting, no doubt, on the suggestion of some of his French allies, he made a list of the inhabitants, drew on each for a definite quantity of supplies, and had these deposited at Meloche's house near his camp on Parent's Creek. A commissary was appointed to distribute the provisions as required. In payment he issued letters of credit, signed with his totem, the otter. It is said that all of them were afterwards redeemed; but this is almost past belief in the face of what actually happened.
