This was not the island in the straits bearing that name, but a stockaded fort on the south shore of Michigan, directly across the strait from St. Ignace. To this day, searching along a beach of deep, yielding sand, so different from the rocky strands of the islands, you may find at the forest edge a cellar where the powder house stood, and fruit trees and gooseberry bushes from gardens planted there more than two hundred years ago. Michilimackinac, succeeding St. Ignace, had grown in importance, and was now a stockaded fort, having French houses both within and outside it, like Detroit. After Father Marquette's old mission had been abandoned and the buildings burned, another small mission was begun at L'Arbre Croche, not far west of Fort Michilimackinac, such of his Ottawas as were not scattered being gathered here. The region around also was full of Chippewas or Ojibwas. All these Indians hated the English. Some came to the fort and said to a young English trader named Alexander Henry, who arrived after the white flag was hauled down and the red one about to be hoisted:-- "Englishman, although you have conquered the French, you have not conquered us. We are not your slaves. These lakes, these woods and mountains were left to us by our ancestors. They are our inheritance, and we will part with them to none!" Though these Ottawas and Chippewas were independent of those about Detroit, they had eagerly taken hold of Pontiac's war belt. The missionary priest was able for a while to restrain the Ottawas. The Chippewas, gathered in from their winter's hunting, determined to strike the first blow. On the fourth day of June, which was the English king's birthday, they came and invited the garrison to look at a game of ball, or baggattaway, which they were going to play on the long sandy beach, against some Sac Indians. The fortress gates stood open. The day was very warm and discipline was relaxed. Nobody noticed that squaws, flocking inside the fort, had tomahawks and scalping knives hidden under their blankets, though a few Englishmen afterward remembered that the squaws were strangely huddled in wrappings on a day hot for that climate. The young English trader, Alexander Henry, has left a careful account of the massacre at Fort Michilimackinac. He did not go out to see the ball game, because he had important letters to write and send by a canoe just starting to Canada. Officers and men, believing the red tribes friendly, lounged about unarmed. Whitewashed French houses shone in the sun, and the surge of the straits sounded peacefully on the beach. Nobody could dream that when the shouting Indians drove the ball back from the farthest stake, their cries would suddenly change to war whoops.
