September 17, 2017 all-day
Sept 17, 1862. This date has been called Americas bloodiest day in recognition of the high casualties suffered in the Civil War battle between General Robert E. Lees Confederate forces and General George McClellan’s Union army. Estimates vary, but more than 25,000 Union and Confederate soldiers were killed or wounded in this battle on the banks of the Potomac River in Maryland.
