• Symbolism
  • Shield: The Regiment took part in the eastern campaigns of the Civil War, its outstanding feats being at Williamsburg, Virginia, 1862, when it assaulted intrenched works, and at Fairfield, Pennsylvania, 1863. At Fairfield the unit engaged two enemy brigades of cavalry, completely neutralizing them and saving the supply trains of the Army, but in the process was literally cut to pieces. This is symbolized by the unicorn, held to represent the knightly virtues and, in the rampant position, a symbol of fighting aggressiveness, combined with speed and activity. The shield is blue, the color of the Federal uniform in the Civil War.
  • Crest: The Chinese dragon represents the Regiment’s entrance into the Forbidden City in Peking in 1900. The arrows symbolize service in the Indian Wars.
