Lieutenant Bramhall had posted his gun near the centre of the line, and opened fire to the best advantage possible. When he mounted the piece, he had eight artillerists, three riders, a corporal and sergeant. In ten minutes, five of these were shot down; in the end, all but two were killed, wounded or missing. Lieutenant Bramhall himself was severely wounded, but stood by his gun. Colonel Coggswell saw the necessity of the case, informed Colonels Wistar and Lee, Adjutant Harvey (of Baker’s brigade), and Stewart (of General Stone’s staff, present on the field); and those five distinguished officers and determined men manned the piece themselves. Coggswell and Harvey, understanding the business, would load, while Lee and Wistar were giving orders to their commands, and spurring them into the fight; then Wistar and Stewart would wheel the gun forward to position; Coggswell would take aim and give the word to Harvey, who held the percussion lanyard. In this way and by these men a dozen of the twenty rounds used were fired, doing more effect than all the musketry volleys. When the enemy was making his fifth charge on the left, the cannon had just been loaded and was pointed at the woods in front. Captain Beiral, of the Californians, who was with his company supporting the piece, exclaimed to Coggswell, “Look to the left! look to the left!” Coggswell saw the dark column of the rebels sweeping across the spur of the field, wheeled the terrible gun around, and discharged it square at their centre. The shell opened a lane through the charging force, a score or more falling never to fight again, and the column retreated upon the main body behind.
