Thomas Andrew Jackson (March 2, 1829 – February 15, 1908) was an American farmer, Republican politician, and Wisconsin pioneer.
In 1854, he became involved with the Pennsylvania state militia and was captain of a Fayette County company known as the Falls City Guards.
He remained there only briefly though, spending most of 1859, 1860, and 1861 working as a farmer at the "Scotch Settlement" just south of the Illinois border.
That fall, he and his brother returned to Green County, Wisconsin, where they commenced organizing a company of volunteers in Spring Grove.
[3] The 18th Wisconsin Infantry mustered into federal service on March 15, 1862, and arrived at Pittsburg Landing, Tennessee, on April 5.
They eventually reformed a line of battle with other regiments of their division and fought for several hours in this position until the enemy had surrounded them on three sides.
[1][4] After returning from the war, Jackson was elected town clerk of Spring Grove in April 1866 and held that office for seven terms.
His brother Charles H. Jackson, who served with him in the Union Army, rose to the rank of lieutenant colonel.
