"John Holloman, the money lender of Company B, was the chief conspirator and leader in the raid and custodian and distributor of the cartridges, but his plans could not have been carried out had not Sergeant George Jackson, of Company B, in charge of the keys of the gun racks in B barracks, and Sergeant Reid, in command of the guards, co-operated both before and after the raid.
"The four men who led the raid were John Holloman, John Brown, Boyd Conyers, and Carolina de Saussure, all of Company B (and probably R.L. Collier, of Company C). Holloman was in barracks, Brown in the bake shop, Conyers and De Saussure in the guardhouse. The two latter were in the same detail, and had been relieved at about 11 o'clock, de Saussure on the post at the guardhouse, and Conyers on No. 2, around the barracks and facing the town. Holloman got the party together. Conyers and De Saussure slept on the same bunk in the guardhouse, claiming that they wanted to get under the mosquito net, and they had the trick of taking their guns into the bunk instead of placing them in the open rack, on the excuse that they didn't rust so badly under cover, but really so the absence of the guns from the open guardhouse rack would not attract attention, and their own absence would be ascribed to a visit to the closet, which was back of the guardhouse. These two men slipped out the rear door of the guardhouse, passed through the sally port, and joined Holloman and Brown.
"The party crossed the wall of the fort down near the end of A barracks, went up the roadway to the entrance to the Cowen alley, where the signal shots were fired. These shots were immediately tallied onto by the alarm shots of Joseph B. Howard, guard on No. 2, and formed the series testified to by Mrs. Katie E. Leahy, of Brownsville. Her testimony is further borne out by the statement that not over thirty seconds elapsed before a number of men of Company B swarmed out on the upper gallery and opened a fusillade on the town.
"It is an absolute certainty that it would have been impossible for Sergeant Jackson to have opened the gun racks, for the men to have assembled, secured their guns, loaded them, gone out to the gallery, and started firing, all after the first shot was fired; all aroused, as they testified unanimously, from sound slumber, in less than two minutes, in the confusion of a dark barrack room. Beyond the possibility of a doubt, the racks had been opened and the inside conspirators were ready to pour out on the signal shots. The testimony is ample that there were scarcely twenty seconds between the last of the signal shots and the first general volley from B barracks.
"The number firing from the barracks is unknown, but perhaps 20 men were involved. A smaller number went to the ground and followed the leaders up the alley. It will be remembered that one of the witnesses testified to hearing some one of the group of soldiers exclaim, 'There they go!' Whereupon these men leaped over the wall and ran up the alley.
"Boyd Conyers is the man whose gun jammed at the exit of the alley by the Cowen house, testified to by Herbert Elkins, and it was taken from him by De Saussure and fixed in the street where the light from the street lamp at the corner of Elizabeth Street shone on them.
"Less than five minutes elapsed from the time the first shot was fired until these men were all back inside the fort.
"Conyers stated that Reid was told that they were going to shoot up the town, and he had laughed and said, 'Don't go out there and let the crackers get the best of you.'
"When Conyers and De Saussure reached the guardhouse they ran in the back way and got into their bunks. Sergeant Reid came in and swore at them, but Conyers was so excited and out of breath that he could hardly stand, so Reid stationed him at the rear of the guardhouse in the dark where he could not be scrutinized so closely.
