St. Joseph was located at the mouth of the river St. Joseph, near the southern end of Lake Michigan.[52] Ensign Schlosser was in command with a mere handful of soldiers, fourteen in number. On the morning of May 25th the commander was informed that a large "party" of Pottawottomis had arrived from Detroit "to visit their relations," and the chief (Washashe) and three or four of his followers wished to hold a "friendly talk" with the commander. Disarmed of suspicion, the commander-ensign admitted the callers; the result is the oft-repeated story. The entering Indians rushed to the gate, tomahawked the sentinel, let in their associates, who instantly pounced upon the garrison, killed eleven of the soldiers, plundered the fort, and later carried Schlosser and his three surviving companions captives to Detroit. Fort Michilimackinac was the most important point on the Upper Lakes, commanding as it did the Straits of Mackinac, the passage from Lake Huron into Lake Michigan. Great numbers of the Chippewas (Ojibwas), in the last of May, began to assemble in the vicinity of the fort, but with every indication of friendliness. June 4th was King George's birthday. It must be celebrated with pastimes. The discipline of the garrison, some thirty-five in number, was relaxed. Many squaws were admitted as visitors into the fort, while their "braves" engaged in their favorite game of ball just outside the garrison entrance. It was a spirited contest between the Ojibwas and Sacs. Captain George Etherington, commander of the fort, and his lieutenant, Leslie, stood without the palisades to watch the sport. Suddenly the ball was thrown near the open gate and behind the two officers. The Indians pretending to rush for the ball instantly encircled and seized Etherington and Leslie, and crowded their way into the fort, where the squaws supplied them with tomahawks and hatchets, which they had carried in, hidden under their blankets. Quick as a flash, the instruments of death were gleaming in the sunlight, and Lieutenant Jamet and fifteen soldiers and a trader were struck down, never to rise. The rest of the garrison were made prisoners and five of them afterward tomahawked. All of the peaceful traders were plundered and carried off. The prisoners were conveyed to Montreal. The French population of the post was undisturbed. Captain Etherington succeeded in sending timely warning to the little garrison at La Baye; Lieutenant Gorrell, the commandant, and his men were brought as prisoners to the Michilimackinac fort and thence sent with Etherington and Leslie to the Canadian capital. The little post of Ste. Marie (the Sault) had been partially destroyed and abandoned. The garrison inmates had withdrawn to Michilimackinac and shared its fate.
