Whereas, The President of the United States, by his proclamation of 15th April, 1861, has called upon me, the Governor of Maryland, for four regiments of infantry or riflemen to serve for a period of three months, the said requisition being made in the spirit and in pursuance of the law, and

Whereas, To the said requisition has been added the written assurance of the Secretary of War, that said four regiments shall be detailed to serve within the limits of the State of Maryland, or for the defence of the Capital of the United States and not to serve beyond the limits aforesaid;

Now, therefore, I, Thomas Holliday Hicks, Governor of Maryland, do, by this my proclamation, call upon loyal citizens of Maryland to volunteer their services to the extent of four regiments, as aforesaid, to serve during a period of three months within the limits of Maryland, or for the defence of the capital of the United States, to be subject under the conditions aforesaid, to the orders of the Commander-in-chief of the army of the United States.
