James Cameron was a Pennsylvanian who served as colonel of the 79th New York Volunteer Infantry Regiment of the Union Army during the early days of the American Civil War . He was the brother of Simon Cameron, United States Senator and first United States Secretary of War in the cabinet of President Abraham Lincoln. At the age of 61, James Cameron was killed in action at the First Battle of Bull Run, the first large battle of the war, on July 21, 1861.
James Cameron was born on March 1, 1800 in Maytown, Lancaster County, Pennsylvania. His parents were Charles Cameron and Martha Pfoutz. His older brother, Simon, was born a year earlier, on March 8, 1799. When James was eight years old, the family moved to Northumberland County, Pennsylvania where his father died within the year at Lewisburg, Pennsylvania. His mother was left with eight children and without means of support. Simon and James thus had to make their way in the world at an early age.
