45th Regiment, Mississippi Infantry

Brief History
45th Infantry Regiment was formed during the late summer of 1862 by redesignating Hardcastle's 33rd Mississippi Infantry Regiment. For a time it was consolidated with the 32nd Regiment. On July 14, 1864, it was consolidated into five companies and became known as the 3rd Battalion, Mississippi Infantry (Williams'). Colonel Aaron B. Hardcastle, Lieutenant Colonel Richard Charlton, and Major Elisha F. Nunn were in command.

The 45th Mississippi Infantry (aka 3rd Battalion MS Infantry[Hardcastle’s/Williams’, &amp; aka 33rd MS Infantry [Hardcastle’s]) ]Internet site has a longer history taken from Dunbar Rowland's Military History of Mississippi, 1803-1898.

Regiment Companies with the County of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.

A list of companies and a link to the rosters will be found with the 3rd Battalion, Mississippi Infantry.
