The red fess with arrow commemorates the battle of Tippecanoe; the battle of Lundy's Lane is shown by the seven cannons captured there; while the border of green, white and red is for the Mexican War. The crest is a modification of the crest of General Nelson A. Miles who led the regiment in several notable Indian engagements. His crest is an arm in armor grasping an anchor; 9 arrows, one for each Indian campaign, is substituted for the anchor in the regimental crest.
