About the Second Pennsylvania Provisional Heavy Artillery Regiment
The regiment was created from the Second Pennsylvania Heavy Artillery, which had served since early 1862 as garrison troops in the defenses of Washington. Although highly trained at firing the heavy siege artillery of the forts around Washington, none of the men had seen combat. By April of 1864 the regiment had grown to over 3,300 men, the largest regiment in the United States Army and three times the legal limit for a heavy artillery regiment.
Grant’s new campaign with its heavy casualties needed front line soldiers and the threat to Washington seemed to be over. It was decided the “Heavies” would be stripped from the Washington garrison and go to war as infantry. First the regiment was split in half, with the ‘new’ regiment to be referred to as the Second Pennsylvania Provisional Heavy Artillery. Even then, both resulting regiments were several times the size of veteran regiments in the field.
The Second Provisional was moved south to the battle front and attached to the First Division of the Ninth Corps. It took part in the battles of the Overland Campaign, operating as infantry. The inexperienced men took heavy casualties at Cold Harbor and in the initial assault on Petersburg, but especially at The Crater where almost two thirds of the regiment was lost.
The regiment was commanded at the Battle of the Crater by Lieutenant Colonel Benjamin G. Barney. When Barney was wounded Captain James W. Haig took command.
At the end of August the regiment had lost a thousand casualties. It disbanded and was reabsorbed into the parent 2nd Pennsylvania Heavy Artillery, which had itself lost half of its 1,800 men.
