The Eleventh Regiment of Infantry, Maryland Volunteers, was organized at Baltimore, Md., June 16, 1864, to serve one hun- dred days. They were really emergency men, called into the military service of the United States at the special request of the Secretary of War, under special agreement by the President of the United States with the Governors of the States of Ohio, Indiana, Illinois, Iowa, Wisconsin and Maryland, for the purpose of relieving certain troops in garrison, to enable them to at once proceed to the front. The 11th Regiment of Infantry proceeded to Monocacy Junction, Md., on the 1st day of July, 1864, where, on the 9th day of July, 1864, it took part in the battle of Monocacy with the troops under General Wallace, who was compelled to fight an overwhelming force of the enemy in order to gain time for reinforcements from the Army of the Potomac, to reach Washington and save the Capitol of the Nation from capture by the enemy then invading Maryland.
After the battle of Monocacy the 11th Regiment of Infantry performed guard duty at Monrovia and Mt. Airey until October 1, 1864, when it was mustered out of the military service of the United States by reason of the expiration of its term of enlistment. The 11th Regiment of Infantry, one year's men, were composed, in part, of the 11th Regiment of Infantry, one hundred days' men, who re-enlisted for one year just prior to the expiration of the term of their original enlistment.
These re-enlisted men constituted three companies, namely, Companies A, B and C, and were, in January, 1865, consolidated with seven companies of the 1st Eastern Shore Regiment of Infantry, Maryland Volunteers, making the regimental organization com- plete again.
Company C was then assigned to duty at the Relay House on the Baltimore & Ohio Railroad, Company I in Baltimore City, and the balance of the regiment was sent to per- form garrison duty at Fort Delaware.
The 11th Regiment of Infantry, as then constituted, was mustered out of service at Baltimore, Md., June 15, 1865. All members whose term of service expired subsequent to October 1,1865, were transferred to the 2d Regiment of Infantry, Maryland Volunteers. The casualties in the 11th Regiment Infantry, Maryland Volunteers, both one hun- dred days' and one year men, were as follows, viz.: Died of wounds, disease, etc., twenty-nine enlisted men.
