Letters, chiefly dating from 1861 to 1862, from Joseph W. Collingwood to his wife Rebecca. Most letters were written over two or three days. The detailed and candid letters cover various aspects of the campaigns and battles Peninsular Campaign (March-July, 1862): the siege of Yorktown, battle of Hanover Court House, Seven Days Battles (June 25-July 1), operations around White House Landing (June 26-July 2); 2nd Battle of Bull Run, Antietam, Sheperdstown Ford, and the Fredericksburg Campaign. His letters provide detailed accounts of camp life of a Civil War soldier payments, uniforms, rations, foraging and procurement, diseases, firearms, drills and inspections, picket duty; roads, recreations, hospitals, and medical care. Collingwood also at length discussed lady nurses and surgeons; Confederate prisoners; socializing with Confederate soldiers; encounters with Confederates and Unionists of Virginia and Maryland, and recounted news from other regiments, especially 29th and 32nd Massachusetts.
Collingwood, an avid admirer of George B. McClellan, filled his letters with discussion of commanders McClellan, Martindale, Barnes, Porter, Pope, and others, together with quite emotional reaction to the dismissal of McClellan and Porter, as well as news of the officers of Massachusetts regiments, including the scandalous, reputation of Ebenezer W. Peirce of 29th Mass. Of special importance is his take on political news and home front: abolitionism, congressional elections of 1862, charity works and recruitment in Massachusetts.
