The Oath I signed stated that I declared Allegiance to the United States, the President and the Constitution above all else and against all enemies both foreign and domestic.

here is an example of an early oath:

"During the Revolutionary War, oaths of allegiance were administered to officers of the Continental Army, pursuant to a Congressional resolution of February 3, 1778.[11] An example appears below.

I James Glentworth, Lieut, of 6th Pennya. Reg. do acknowledge

the UNITED STATES of AMERICA to be Free, Independent and Sovereign States, and declare that the people thereof owe no allegiance or obedience to George the Third, King of Great Britain; and I renounce, refuse and abjure any allegiance or obedience to him; and I do Swear that I will, to the utmost of my power, support, maintain and defend the said United States against the said King George the Third, his heirs and successors, and his or their abettors, assistants and adherents, and will serve the said United States in the office of Lieutenant which I now hold, with fidelity, according to the best of my skill and understanding.

JAMES GLENTWORTH.

Sworn at the Valley Forge Camp this 11th day of May, 1778, before me

STIRLING, M. G.[12]"
