Colonel Corcoran at once resumed command of the regiment and issued General Order No. 1, an historic order concluding with the words: “The Commandant feels proud that his first duty after being relieved from a long arrest is to have the honor of promulgating an order to the regiment to rally to the support of the Constitution and Laws of the United States.” Within twenty-four hours from the posting of this order, six thousand men had volunteered, but the instructions of Governor Morgan prohibited the enlistment of more than the regimental compliment of one thousand men. The twenty-third of April, 1861, dawned bright and clear, but warmer than usual at that season, over the Empire City; apprehension and gloom prevailed throughout the country; ten sovereign states had formed a powerful confederacy and were in armed revolt against the authority of the Federal Government. Many of the ablest soldiers and statesmen of the Republic had taken their stand against the Union; the timid were upon the verge of panic, and misgivings and uncertainty were paralyzing even the resolute and strong. Under such circumstances, faithful and loyal, the gallant Sixty-ninth Militia assembled in Prince Street, near the then St. Patrick’s Cathedral, the Cathedral of the great Archbishop of New York, the Most Reverend John Hughes, and proceeded thence to the rendezvous at Great Jones Street. Hope was given to the hearts of the good people of this city as they witnessed the spirit displayed by this brave body of citizen soldiery, and when at the appointed hour, the order to march was sounded and the regiment proceeded down Broadway to the strains of martial music, the surging multitude that lined the streets, the myriad spectators that filled the windows along the route to Cortlandt Street broke into continuous cheers. Twin flags floated everywhere on that day. Twin banners were carried by the regimental standard bearers—the flag of Columbia with all its stars emblazoned on its field of blue, the green banner of Erin with the harp uncrowned. The regiment boarded the Steamer “James Adger,” at Pier 4, North River, reached Annapolis on the twenty-sixth of April, and proceeding up the Potomac to Washington by Steamer “Marion,” was mustered into the service of the United States on May 9 for three months.
