As most who are familiar with the battle know, Ricketts's and Griffin's battery were sent forward onto Henry House Hill in an exposed position, over the objections of a batteries commanders. At one point an infantry force approached Griffin's battery. Griffin was sure they were Confederates; artillery chief William Barry was convinced they were Union infantry supports. The infantry opened fire, decimating the battery. A bullet struck Ames in the thigh. As Griffin wrote in his official report: "I deem it my duty to add that Lieutenant Ames was wounded so as to be unable to ride a horse at almost the first fire; yet he sat by his command directing fire, being helped on and off the caisson during the different changes of front or position, refusing to leave the field until he was too weak to sit up."
In 1894, Ames was awarded a Medal of Honor for his actions at Bull Run. His citation reads:
The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to First Lieutenant (Field Artillery) Adelbert Ames, United States Army, for extraordinary heroism on 21 July 1861, while serving with 5th U.S. Artillery, in action at Bull Run, Virginia. First Lieutenant Ames remained upon the field in command of a section of Griffin's Battery, directing its fire after being severely wounded and refusing to leave the field until too weak to sit upon the caisson where he had been placed by men of his command.
