46th Regiment, Mississippi Infantry
46th Infantry Regiment was organized during the fall of 1862 by adding four companies to the six-company 6th (Balfour's) Mississippi Infantry Battalion. In February, 1863, it totalled 407 effectives and served in S.D. Lee's and Baldwin's Brigade in the Department of Mississippi and East Louisiana. The unit participated in the long Vicksburg siege and was captured on July 4, 1863. After the exchange it was assigned to General Baldwin's, Tucker's, and Sears' Brigade. It fought in the Atlanta Campaign, endured Hood's winter operations in Tennessee, and shared in the defense of Mobile. The regiment had 1 wounded at Chickasaw Bayou and during the Atlanta operations, May 18 to September 5, reported 23 killed, 68 wounded, and 37 missing. It lost 1 killed, 13 wounded, and 16 missing at Allatoona and had many disabled at Franklin. Only a remnant surrendered in May, 1865. The field officers were Colonels William H. Clark and Claudius W. Sears, Lieutenant Colonel William K. Easterling, and Major Constantine Rea. 
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.
