On both sides the casualties among officers in the battle of Antietam was unusually numerous. Among the rebel killed were Brigadier-Generals Starke and Branche, and among their wounded were Major-General Anderson, Brigadier-Generals Anderson, Lawton, Wright, Ripley, Amistead and Ransome. The Union army was called upon to mourn the loss, among many other valuable officers, of Brigadier-General Isaac P. Rodman, of Rhode Island. He had left the quiet pursuits of business, and volunteered in defence of the Government. He entered the service in one of the regiments of his native State as Captain, and was quickly promoted to a Colonelcy, and led his regiment in General Burnside’s North Carolina expedition. He was made a Brigadier for services at Roanoke and Newbern, and was mortally wounded while acting as division commander at Antietam. The loss of the Federal army in this terrible battle bears ample testimony to its courage and endurance. From the official records the total loss in killed was two thousand and ten; missing, one thousand and forty-three; total, twelve thousand and sixty-nine. The combined loss at South Mountain, Antietam and Harper’s Ferry, was twenty-six thousand three hundred and ninety-four. The report of General McClellan estimates the rebel loss in Maryland at thirty thousand men. General Burnside, whose corps was stationed on the left of the Federal lines, testified before the investigating committee of Congress, that at half-past eight o’clock in the evening of the 17th, he went over to McClellan’s headquarters, and urged the renewal of the attack, saying that with five thousand fresh troops to place beside his own, he was willing to commence the attack in the morning. As his corps had maintained the most critical position during the battle, and had defended the salient points with remarkable bravery and endurance, while suffering heavy loss, it may not be amiss to record his testimony in this place. General Franklin, whose corps occupied a position on the right of the Federal lines, also gave testimony before the Commission in the following terms: “When General McClellan visited the right in the afternoon, I showed him a position on the right of this wood, which I have already mentioned, in which was the Dunker church, which I thought commanded the wood; and that if it could be taken, we could drive the enemy from the wood, by merely holding this point. I advised that we should make the attack on that place the next morning from General Sumner’s position. I thought there was no doubt about our being able to carry it. We had plenty of artillery bearing upon it. We drove the enemy from there that afternoon, and I had no doubt we could take the place the next morning, and I thought that would uncover the whole left of the enemy.”
