The 24th of October was the day appointed for taking possession of Harper's Ferry, but fear of exposure led to a change of plan and the move was begun on the 16th of October. Six of the party who would have been present at the later date were absent. The march from Kennedy farm began about eight o'clock Sunday evening. Before midnight the bridges, the town, and the arsenal were in the hands of the invaders without a gun having been fired. Before noon on Monday some forty citizens of the neighborhood had been assembled as prisoners and held, it was explained, as hostages for the safety of members of the party who might be taken. During the early forenoon Kagi strongly urged that they should escape into the mountains; but Brown, who was influenced, as he said, by sympathy for his prisoners and their distressed families, refused to move and at last found himself surrounded by opposing forces. Brown's men, having been assigned to different duties, were separated. Six of them escaped; others were killed or wounded or taken prisoners. Brown himself with six of his men and a few of his prisoners made a final stand in the engine-house. This was early in the afternoon. All avenues of escape were now closed. Brown made two efforts to communicate with his assailants by means of a flag of truce, sending first Thompson, one of his men, with one of his prisoners, and then Stevens and Watson Brown with another of the prisoners. Thompson was received but was held as a prisoner; Stevens and Watson Brown were shot down, the first dangerously wounded and the other mortally wounded. Later in the afternoon Brown received a flag of truce with a demand that he surrender. He stated the conditions under which he would restore the prisoners whom he held, but he refused the unconditional surrender which was demanded.
