Hi David -
below is a standard loyalty oath (this one taken from a railroad pass) administered to CSA POWs:
"The undersigned accepts this pass on his word of honor that he is loyal to the United States and if he is hereafter found in arms against the government of the United States or aiding or abetting its enemies, the penalty will be DEATH."
Sorta scary when you realize this is the Federal Government talking....
:-)
