Ladies and Gentlemen,
Don't mean to sound mean but, it is spelled CAVALRY. I have seen this butchered over and over again in various message boards and as a 21st Century U.S. Army CAVALRY Officer and a Southerner who had an ancestor that rode in the CAVALRY it pains me.
CAVALRY is the branch of service that used mobility, shock, and firepower in order to provide the commander with timely information, security, and maneuver on the battlefield.
CALVARY is the hill Christ was crucified upon the cross. Also known as in Aramaic as Golgotha (the place of the skull). In the Vulgate a Latin word for "skull", calvaria, is the source of the English use of in the King James Version of the Holy Bible (Luke 23, verse 33).
As it relates to research, if someone is trying to find your post typing in "CAVALRY" in their search engine, your potentially helpful post that they may be able to use or help you with, would be missed because of the misspelling.
