The 1865 leather bound, preprinted, pocket diary contains one entry per day with cash accounts and notes listed in the back of the book. This diary continues with the 141st PA Volunteers camped outside of Petersburg in their winter quarters and continues through the end of the war and Peck's return home. He recounts the fall of Petersburg, the Union pursuit of Lee's Army of Virginia across the state, and Lee's ultimate surrender at Appomattox Court House. Peck was assigned to preside over several court martial proceedings and gives details regarding these proceedings and punishments, which include a botched execution of a Union soldier. As in the first diary, Peck provides an account of the daily movement of Union troops and supplies. He also gives detailed lists of captured soldiers and artillery, as well as Union wounded and casualty records. As the war nears its conclusion Peck was in charge of mustering out soldiers and kept thorough records of the process. He also recounts receiving the news of Presidents Lincoln's assassination and describes the mood of the men upon hearing the President was killed. The entries end in July of 1865 with Peck practicing law in his home town of Towanda, PA.
