The Grand Review of the Armies happened on May 23rd and 24th, 1865 after the formal end of The Civil War. Much of the Union Army paraded through the streets of Washington (most importantly, Pennsylvania Ave.), much to the cheers and adulation of the crowd. The country had just been through four horrible years of war, capped off by the assassination of their beloved president at Ford’s Theatre just a month earlier.
The officers in these armies had not seen each other for many years and were able to reconnect in the city, while enlisted infantrymen spent their time eating and drinking in the local establishments, often coming to blows over which army was superior.
