      Delaware, especially considering its small size, provided a large number of fighting men to the Union cause during the American Civil War.

      The best sources within the State archives indicate that there were 11,236 white soldiers, 94 sailors and marine and a total of 954 black soldiers from the First State.   That makes a grand total of " 12,284 Delawareans who fought for the Union " out of total state population (male and female) of about 110,000 total according to the 1860 census.   This number includes all branches of service ..... artillery, infantry, cavalry along with the marines and sailors.

      This article will provide short descriptions of the various infantry units only.   These infantry units were divided into two different categories at that time.   These two were the " Volunteer Militia " and the " Wartime Organizations ".

      The " Volunteer Militia " consisted of the units which were formed in whole or in large part from organizations which had existed prior to the start of the American Civil War.   The State of Delaware had abandoned the previous policy of universal militia service which had been in place since 1829.   The state now relied on the " Volunteer Company Act " of the year 1845 to provide state defense.

      This act allowed the local companies to form into complete battalions and regiments of volunteer militia.   By the year 1860, Delaware had many volunteer militia companies which had been active for a number of years.   It was these volunteer organizations which became the nucleus for the First and Second Delaware Volunteer Infantry Regiments, and why these two regiments were able to organize so quickly when the call came.

      The first four below regiments, " 1st, 2nd, 3rd, and 4th Delaware Regiments " all saw combat from the spring of 1862 through the end of the Civil War.   They took part in all the major operations in the eastern theater of the war.   They all suffered heavy casualties at the major Battles of Antietam, Fredericksburg, Chancellorsville, Gettysburg, The Wilderness and Petersburg.

      The 5th, 6th, 7th, 8th, and 9th Delaware Regiments and their duties are also listed below !

First Regiment Delaware Volunteers

      Under President Abraham Lincoln's first call for volunteers, 75,000 men were needed for three months service to " put down the rebellion. "   Delaware's quota of this first call for volunteers was 780 men.   This was rapidly met by the formation of the First Regiment Delaware Volunteers which was mustered into Federal service on May 28, 1861.

      At that time it had 37 officers and 742 enlisted men under the command of " Colonel Henry Hayes Lockwood ".   This 90 day unit was mustered out early on August 17, 1861.

Second Regiment Delaware Volunteers

          Shortly after that first call to arms, when the more serious nature of the war began to show itself, there was a second call, this time for 300,000 three year men.

      The Second Regiment Delaware Volunteers  ~  " The Crazy Delawares "  ~  was the state's response to this call.   They were mustered in on May 21, 1861 under Colonel W. H. Wharton and Lt. Col. William P. Bailey.   In order to respond as rapidly as they did (and thus filling the state's second quota) four companies were recruited from nearby counties in Maryland and Pennsylvania.

      Companies B, D and G were from Philadelphia, Pennsylvania and Company C was from Elkton, Maryland.   The Second Delaware mustered in with 33 officers and 805 men.   The Crazy Delawares fought in all the major campaigns of the Army of the Potomac.   The mustering out took place between July 1st and October 1st of 1864.   This was due to the late addition of the last four companies to the regiment in October of 1861.
