Fairfax Court House and Centreville, crossing the Potomac at Chain Bridge, and marching to Tenallytown, Rockville and Frederick City, Maryland, crossing South Mountain to Antietam, participating in that battle and leaving two hundred and one of its members either killed or wounded to testify to the character of the resistance offered by these sons of the Gael to the rebel line in front of the “Bloody Lane.” On December 13th the regiment constituting part of Meagher’s Brigade took part in the desperate attempt to carry the impregnable position of the Confederate forces on Marye’s Heights at Fredericksburg. The valor displayed by the officers and men on this memorable day must dwell forever in the memory of mankind. Inspired by the traditions of the old brigades, the brigades of O’Brien, Dillon, Lally, Sarsfield, the brigades of Landen, Ramilles and Fontenoy; aroused by the burning eloquence and encouraged by the intrepid daring of their fearless leader; mindful of the wrongs which exiled them from their native shores; grateful to the free, fair land that welcomed them to home and liberty, there was no danger too great for them to face, no suffering too severe to endure, no odds too overwhelming to encounter. Five hundred and forty-five soldiers of the Irish Brigade fell in that heroic charge in that most bloody quarter of a mile ever dashed over by armed men in the annals of civilized warfare. The testimony of the _London Times_ correspondent will be regarded at least as not coming from an unduly partial source. This is his description of the charge of the Irish Brigade: “Never at Fontenoy, Albuera, nor at Waterloo was more undaunted courage displayed than during those six frantic dashes which the Irish Brigade directed against the almost impregnable position of their foe. That mortal man could have carried the position, defended as it was, seems idle for a moment to believe, but the bodies which lie in dense masses within forty-eight yards of the muzzles of Colonel Walton’s guns are the best evidence of what manner of men they were who pressed onto death, with the dauntlessness of the race which has gained glory on a thousand battlefields and never more richly deserved it than at the foot of Marye’s Heights on the 13th day of December, 1862.” In his official report General Meagher says: “Of the 1,200 men I took into action, only 280 appeared on parade next morning.”
