Already the war had become a reality to these Yankee lads. Lincoln’s call for men was issued on April 15, 1861. Massachusetts had four regiments ready. The first of these reached Baltimore four days after the President’s Proclamation. Three men were killed by a mob, and thirty were injured as they marched through Baltimore. The regiment fought its way to the station, regained possession of their locomotive and train, and moved on to Washington. Clara Barton’s first service to the soldiers was only incidentally to the wounded. There were only thirty of them, and they were adequately cared for. But she, in company with other women, visited the regiment at the Capitol, and she performed her first service to the armies of her country by reading to the homesick boys as they gathered in the Senate Chamber, and she stood in the place that was ordinarily occupied by the Vice-President of the United States. Her own account of this proceeding is contained in a letter to her friend, B. W. Childs: WASHINGTON, April 25th, 1861 MY DEAR WILL: As you will perceive, I wrote you on the 19th, but have not found it _perfectly convenient_ to send it until now, but we trust that “navigation is open now” for a little. As yet we have had no cause for alarm, if indeed we were disposed to feel any. The city is filling up with troops. The Massachusetts regiment is quartered in the Capitol and the 7th arrived to-day at noon. Almost a week in getting from New York here; they looked tired and warm, but sturdy and brave. Oh! but you should hear them praise the Massachusetts troops who were with them, “Butler’s Brigade.” They say the “Massachusetts Boys” are equal to anything they undertake--that they have constructed a railroad, laid the track, and built an engine since they entered Maryland. The wounded at the Infirmary are all improving--some of them recovered and joined the regiment. We visited the regiment yesterday at the Capitol; found some old friends and acquaintances from Worcester; their baggage was all seized and they have _nothing_ but their heavy woolen clothes--not a cotton shirt--and many of them not even a pocket handkerchief. We, of course, emptied our pockets and came home to tear up old sheets for towels and handkerchiefs, and have filled a large box with all manner of serving utensils, thread, needles, thimbles, scissors, pins, buttons, strings, salves, tallow, etc., etc., have filled the largest market basket in the house and it will go to them in the next hour.
