Thomas Chamberlain (soldier)

Thomas Davee Chamberlain (April 29, 1841 – August 12, 1896) was an officer in the 20th Maine Volunteer Infantry Regiment during the American Civil War, the brother of Union general Joshua L. Chamberlain, the commanding officer of the 20th Maine Infantry.

Early life
Thomas D. Chamberlain was born in Brewer, Maine, the youngest of five children. Young Tom grew up on the family farm in Brewer with his four older siblings: Joshua Lawrence (born in 1828), Horace Beriah (1834), Sarah Brastow (1836) and John Calhoun (1838). Their upbringing seems to have been strict and religious but also loving. Thomas was a mischievous and likable boy - his brother called him a "little rogue" - and, as the baby of the family, he was his mother's favorite. Thomas was the only son not to attend college. Whether this was due to lack of intelligence, application or inclination, is unknown. By his mid-teens Thomas was working as a clerk in a grocery store in Bangor.

Civil War service
Chamberlain's great-grandfathers were soldiers in the American Revolutionary War and his grandfather had served during the War of 1812. His father also had served during the abortive Aroostook War of 1839. His brother Joshua was also in the army.

In 1862, Chamberlain joined the Union Army. His motives were mixed&mdash;personal, patriotic, and religious.

He was soon placed in the newly formed 20th Maine Infantry along with his brother Joshua, who was made lieutenant colonel of the regiment.

The 20th Maine regiment marched to the Battle of Antietam, but did not participate in the fighting. They fought at the Battle of Fredericksburg, suffering light casualties in the assaults on Marye's Heights, but they were forced to spend a miserable night on the freezing battlefield among the many wounded and dead from other regiments. They missed the Battle of Chancellorsville in May 1863 due to an outbreak of smallpox in their ranks, which kept them on guard duty in the rear. In June 1863, Joshua was promoted to colonel of the regiment, after the promotion of its first colonel, Adelbert Ames, to brigade command. Thomas Chamberlain was involved in most of the other battles in which the 20th Maine fought, most notably the Battle of Gettysburg.

The Battle of Gettysburg
During the defense of Little Round Top, the 20th Maine came under heavy attack from the Confederate 15th Alabama regiment, part of the division led by Maj. Gen. John Bell Hood, and after about 3–4 hours of fighting the 20th Maine completely ran out of ammunition. Chamberlain's brother Joshua recognized the dire circumstances and ordered his left wing to respond to the rebels by charging downhill with fixed bayonets, thus ending the Confederate attack on the hill. The 20th Maine and the 83rd Pennsylvania together captured over 400 soldiers from the attacking Confederate forces. Joshua was slightly wounded in the foot by a spent bullet. Thomas was unhurt, except for "several scratches". As a result of their valiant defense of the hill, the Chamberlain brothers, Joshua Chamberlain especially, and the 20th Maine gained a great reputation and they were the subject of many publications and stories

After Gettysburg
After Gettysburg, the major battles in which Thomas Chamberlain and the 20th Maine were involved were the Battle of Spotsylvania Court House and the Siege of Petersburg. At the Siege of Petersburg, the 20th Maine was in reserve, while Joshua (against his better judgment) led his Pennsylvania Bucktail brigade in a charge on a section of the Confederate defenses known as Rives's Salient. Turning to direct his troops, Joshua was struck by a minié ball, which entered just below his right hip, nicked his bladder and urethra, and stopped at his left hip. Such a devastating wound should have been fatal, and when he arrived at the field hospital, three miles behind the lines, his life was feared over. Thomas Chamberlain, back with his regiment, eventually heard the news. He and the surgeon of the 20th Maine, Dr. Abner O. Shaw, went to the hospital where Joshua was dying. As Thomas waited, Dr. Shaw, with Dr. Morris W. Townsend of the 44th New York, worked all night to try to save Joshua Chamberlain's life. Thirty-five years later, Joshua Chamberlain wrote that, after the surgeons had finished: "Tom stood over me like a brother, and such a one as he was." Remarkably, Col. Chamberlain survived to enjoy his "on the spot" promotion to brigadier general, although he never returned to full fitness. A number of biographers of Joshua Chamberlain say that his life was saved through the activity of his brother, Thomas.

Appomattox Campaign
After Petersburg, Thomas Chamberlain and the 20th Maine were involved in the Battle of Five Forks and the Battle of Appomattox Courthouse. At the end of the war, the 20th Maine marched from Appomattox, Virginia, on May 2, reaching Washington, D.C., on May 12, where it was then finally mustered out of service on July 16, 1865.

Postbellum
After the war, despite his distinguished military record, Chamberlain drifted from one job to another. He suffered from alcoholism as well as severe lung disease and heart disease.

Death
Thomas D. Chamberlain died at age 55 in Bangor, Maine. He is buried at Castine, Maine.
