From the time of his departure on February 16, 1863, to join the Union Army until he returned home on July 18, 1865, Louis N. Beaudry kept a detailed diary of the day-to-day events of the Fifth New York Cavalry. The unit was a participant in the Battle of Gettysburg, and Beaudry writes of it in great detail. As the unit's chaplain, Beaudry was very observant of those factors that influenced morale, such as fighting, disease, boredom, hunger and weather conditions; his diary is thus uniquely focused on the daily routine of the Fifth New York.
