This was in the Covington Journal of June 14, 1862 and I thought it was interesting to see the specific language used.
We have thought it best to publish the form of oath which all persons arrested as rebels, or as aiders and abettors of rebellion, or as sympathizers with it, are required to subscribe as a condition of their discharge. It is as follows:
"I do solemnly swear that I will bear true allegiance to the United States, and support and sustain the Constitution and laws thereof; that I will maintain the national sovereignty paramount to all State, county or Confederate powers; that I will discountenance, discourage and forever oppose secession, rebellion and disintegration of the Federal Union; that I disclaim and denounce all faith and fellowship with the so-called Confederate States and Confederate armies, and pledge my honor, my property and my life to the sacred performance of this, my solemn oath of allegiance to the Government of the United States of America."
"Subscribed and sworn to before me, ths __ day of __, 1862."
"The penalty for violation of this oath is death."
