150 years ago this summer substantial monetary incentives were offered to veterans if they would return to the service. From a Seneca County, New York newspaper in August 1863:
CAPT. E.J. TYLER, of the old 33d Regiment, has opened a recruiting office in this village [Seneca Falls], and will enlist all who desire to join the cavalry arm of the service. Very large bounties are offered to veteran soldiers, as will be seen by his advertisement. the men enlisted will go into the First Regiment Veteran Cavalry now being organized by Col. R.F. TAYLOR.
Here’s a (very) rough approximation of the advertisement:
Colonel Taylor raised the 1st New York Veteran Cavalry Regiment and led it until 1864. Captain Tyler is not listed on the roster.
