As the Civil War continued with the great Confederate offensive in the summer and fall of 1862 the fighting became bitter and bloodier. Battles at Second Manassas, Antietam, Perryville, Murfreesboro, Fredericksburg and Chancellorsville were all added to the list of vicious battles fought between men of north and south. The commencement of the great campaigns of Vicksburg in the west and Gettysburg in the east in the spring and early summer of 1863 brought the war to a crises. The amateur soldiers and primitive organizations of 1861 had been forged into modern armies and those armies were poised to fight it out. This session deals with the crucial nine months of the war prior to the Battle of Gettysburg.
