Any notes on the civil war service record of "Archibald Briggs, Co. H, 2 Arkansas Cavalry (Union??) would be appreciated.

Is the above info on Briggs correct and verifiable?

Did he serve under Col. Marcus La Rue Harrison?

Would he have been active around Fayetteville in late 1864, and perhaps ridden with Col. Harrison into Indian Territory during November 1864, under the overall command of MG S. R. Curtis, pushing MG Sterling Price's Confederate raiders out of Arkansas?

Thanks.
