John Smith's Pension File from the war of 1812 makes mention of this incident also.  He was a private in the first Regiment of the Indiana Territory Militia and was under the command of Captain Daniel Comar.  One of the documents reads as follows, "that he [Captain Comar] commanded a company in the Regiment under Col. Robert M. Evans and with a part of his company was stationed at McGowen's ferry on the eastern fork of White River then in the county of Knox Indiana Territory; that John Smith was regularly mustered a private in the said company; that in the beginning probably the fourth day of April, eighteen hundred and thirteen, the deponent detached a party to which the said John Smith belonged, to convey provisions to the station under the deponents command; that within a few miles of the said station, the said detachment was attacked by a party of hostile Indians and the said John Smith, whilst in the discharge of his duty as a soldier was wounded by a rifle or musket ball in the left thigh, the ball entering a little below the hip, and passing through, in, or near the groin".   Another document from the pension records reads "John Smith , who on his oath, declared that he is the same person who formerly belonged to the Company commanded by Capt. Daniel Comar in the Regiment commanded by Col. [Robert M. Evans] in the service of the United States; that his name was placed on the Pension Roll of the State of Indiana from whence he has lately removed; that he now resides in the State of Arkansas, where he intends to remain, and wishes his Pension to be there payable in future. The following are his reasons for removing from the said State of Indiana to wit that the climate being so cold and having lost his wife and two of his children and some of his Grand children from the sickness prevalent there and those being the sole and only reasons for his leaving there".

 

    Also John had a brother, Thomas Smith Jr. that died in Knox Co. IN in 1805, John was administrator of the estate when it was probated. This Thomas left a son, also named Thomas, and in 1808 the court granted custody to the child's grandmother, Rebecca Smith.
