Flagg’s party then went into camp for the rest of the night and in the morning followed on north, passing the TA ranch and reaching Buffalo in the afternoon. Reinforced to 48 men, they rode out to the TA ranch and at daylight on the morning of April 11th, the invaders were completely surrounded. Sheriff Angus had in the meantime returned from the K. C. ranch, having ridden 120 miles in the marvelous time of 14 hours, and reported the shooting of Champion and the burning of Ray’s body. This news greatly increased the prevailing excitement, and during the day of the eleventh a crowd of between three and four hundred well armed and determined men, making a stand in defence of their homes and their liberty, were on the ground to aid in dislodging the enemy. In the absence of the sheriff, Arapahoe Brown and E. U. Snider were placed in command. Monday night was devoted to digging rifle pits and throwing up breastworks around the besieged. Tuesday brought recruits from Sheridan County and the distant parts of Johnson, thus swelling the ranks of the home defenders. Early on Monday morning the cattlemen opened fire on a bunch of settlers 400 yards up the hill, and the battle was on. A brisk fire was kept up most of the time from the opening shot until the final surrender. There was not a cannon in the country save at Fort McKinney, and the commanding officer there refused to loan one to the settlers. Realizing that the fortifications were impregnable to small arms and fearing state interference at an early day, it was determined to construct a moveable breastwork that could be run down the hill sufficiently near the fort to admit of throwing against its walls the dynamite captured from the cattlemen’s supply wagons. For this purpose two of the captured wagons were used. A correspondent on the ground describes this “Go-Devil” as follows: “The idea of building a movable fort or breastwork originated with Arapahoe Brown and E. U. Snider. The running gear of the captured Arp & Hammond wagons, two pair, were placed side by side several feet apart and then fastened together by a framework of logs. The rear of the wagons was the front of the fort and was comprised of two thicknesses of eight-inch logs fastened together by wire. This formed a breastwork over six feet high, with five port holes in it, also protected by eight inch pieces. If necessary baled hay could be placed inside, making the protection still stronger. Five men could slowly move the ingenious contrivance, fifteen could move it easily, and it would protect 40 men. The plan was to move it down upon the white caps near enough to throw giant powder into their fort. It was in working order and had been moved about 100 yards when the soldiers came in sight. All proceeding at once ceased and the men who for 48 hours had held the fighting cattlemen at bay cheered the troops lustily as they advanced to the rescue.”
