English: Encampment of Colonel Ellsworth's New York Fire Zuoaves, on the heights opposite the Navy Yard, Washington, D. C. This famous body of fiery and active soldiers at length got free from the trammels and confinement of their city quarters, a change which was both pleasant and beneficial to them. They were encamped on the heights opposite the Navy Yard, Washington, D. C., and, as our sketch will show, were most comfortably situated. Colonel Ellsworth was indefatigable in drilling his regiment, and his men most willingly seconded his efforts by close attention to duty and alacrity in the performance of all the details of camp life. The Zuoaves proved to be one of the most effective regiments in the field; they rendered efficent service in building breastworks on the outskirts of Alexandria, thereby preyenting the possibility of a surprise from the enemy, and distinguished themselves at the Battle of Bull Run in their successful assault on a confederate battery at the point of the bayonet.
