From the headquarters of these two officers will go forward this morning the orders which will rally the officers and men of these two regiments to their armories for the first general call since the Spanish-American War. In Richmond, the call means the immediate mobilization of the Richmond Grays Battalion, Major J. Fulmer Bright, commanding the Howitzers, commanded by Captain William M. Myers, and the Signal Corps, Lieutenant F. Karle Lutz, acting officer in command. Orders were issued last night to Major Bright and Lieutenant Lutz and to a subordinate officer of the Howitzers, Captain Myers being en route to Detroit, where he has gone to attend the annual convention of the Veiled Prophets. He will be notified in Detroit this morning and will return at once to assume command.
