The design of the regimental shield centers on a
cross moline sable, on a chief embattled of the last a
Maltese cross argent. The field is yellow for the Cavalry.
The cross moline symbolizes the charge of this regiment on
Longstreet's troops at Gaines Mill in 1862; a charge which
saved the Union artillery and which is characterized by the
regimental historian as "its most distinguished service".
The cross moline is supposed to represent the iron pieces
of a mill stone (moulin, the French word for mill). The
chief is for the Puerto Rican Expedition of 1898. The
original name of the island was San Juan, named for the
knights of St. John who wore a white Maltese cross on a
black habit. The partition line is embattled to suggest
the castle on the Spanish arms.
