The following year a bill was finally passed, and approved by Governor Altgeld, which provided for the creation and establishment of the Illinois Naval Militia, to consist of two battalions, each having a maximum strength of 400 men, and a minimum of 140.[2] The 1st Battalion met one evening each week and practiced boat-drill, both sail and oar, and were trained in the use of torpedoes, for which a steam-launch was specially fitted; and in the use of artillery, the cutlass, and small arms.There was also an associate membership, composed of many of the leading merchants, bankers and professional men of Chicago, including Marshall Field, Lyman J. Gage, and Charles Deering.Further, honorary memberships were awarded to Shelby M. Cullom, J. Frank Aldrich, and Colonel Leroy P. Stewart, Inspector General of the First Brigade of the Illinois National Guard.Detailed plans for mobilization were prepared, and within forty-eight hours of the declaration of war on April 6, 1917, the entire Illinois Naval Militia had left Chicago by train for the Philadelphia Navy Yard.
