Much criticism has been indulged in as to whether Captain Marsh, when he became convinced of the general outbreak, should not have retreated to the fort. Of course, forty-five men could do nothing against five or six hundred warriors, who were known to be at or about the agency. The Duke of Wellington, when asked as to what was the best test of a general, said, "To know when to retreat, and to dare to do it." Captain Marsh cannot be justly judged by any such criterion. He was not an experienced general. He was a young, brave, and enthusiastic soldier. He knew little of Indians. The country knows that he thought he was doing his duty in advancing. I am confident, whether this judgment is intelligent or not, posterity will hold in warmer esteem the memory of Captain Marsh and his gallant little band than if he had adopted the more prudent course of retracing his steps. Gen. George Custer was led into an ambush of almost the exact character, which was prepared for him by many of the same Indians who attacked Marsh, and he lost five companies of the Seventh United States Cavalry, one of the best fighting regiments in the service, not a man escaping. Immediately previous to the outbreak Lieut. Timothy J. Sheehan, of Company "C," Fifth Minnesota, had been sent, with about fifty men of his company, to the Yellow Medicine Agency, on account of some disorder prevailing among the Indians; but having performed his duty, he had been ordered to Fort Ripley, and had on the 17th left Fort Ridgley, and on the 18th had reached a point near Glencoe, distant from Fort Ridgley about forty miles. As soon as Captain Marsh became aware of the outbreak, he sent the following dispatch to Lieutenant Sheehan, which reached him on the evening of the 18th: "_Lieutenant Sheehan:_ "It is absolutely necessary that you should return with your command immediately to this post. The Indians are raising hell at the Lower Agency. Return as soon as possible."
