The Andrew Brockway letters were written to his sister, Arelia from Virginia, Maryland, Tennessee, and Georgia, and deal primarily with camp life and troop movements. Brockway describes his many marches in detail, and he offers opinions on President Lincoln ("I did not see as old Abe looked any different from any human being"), Hooker ("There is no lack of faith in our commander... if the authority as Washington will only let him work"), and Meade ("Guess he is a little fearful of taking them [the Confederates] on their own ground").
Although the Brockway correspondence is very incomplete, it includes accounts of the Battles of Rocky Face Ridge and Chancellorsville, the latter written by Brockway's comrade, Ambrose B. Morgan. Brockway's letters from Shelbyville, Tenn., provide interesting commentary on the relations of an army of occupation with the citizens whose land they occupy. The description of a Washington's Birthday party at Shelbyville in 1864 is particularly charming.
