News of the great three-day battle at Gettysburg brought correspondents, artists and photographers flocking to the battlefield. First on the scene were the sketch artists who traveled with the armies and often witnessed the fighting. Frequently working under fire, men like Alfred Waud made quick, detailed sketches of the action for the North’s illustrated newspapers. Only two days after the battle, photographer Alexander Gardner and his assistants arrived with their horse-drawn darkrooms to record the scene, and a week later Mathew Brady reached Gettysburg from New York. Between them Gardner, Brady and their gifted assistants assembled an indelible graphic record of America’s greatest battlefield.
