As a brigadier general in the New Jersey militia, Runyon commanded the Fourth Division of the
Army of Northeastern Virginia in June and July 1861. The division was composed of 90-day New Jersey volunteer regiments and new 3-year New Jersey volunteer regiments which had been organized for less than a month. Union Army commander,
Major General Irvin McDowell held this division in reserve during the
First Battle of Bull Run and they were not engaged in the battle. Although the Historians John and David Eicher show Runyon in charge of the division and as mustered out of the volunteers on July 31, 1861, they do not show him with a formal Union Army commission. Runyon held his position as division commander as a State militia or short-term volunteer general, not as a formally commissioned Union Army general. On February 25, 1862, Runyon was appointed a
brevet major general in the New Jersey militia.
Later career From 1864 to 1866, Runyon served as mayor of Newark as a
Democrat. He had previously been city attorney and city counsel. Runyon was appointed
major general in charge of the
New Jersey National Guard, and served in this post until 1873. He was the first president of the Manufacturers' National Bank of Newark until he became
chancellor of New Jersey, an office he held for 14 years. In 1893, Runyon became envoy and later
ambassador to Germany, where he died in 1896. He is buried at
Mount Pleasant Cemetery in Newark, New Jersey. ==Notes==
