In March 1917, Logan's regiment was mobilized to guard installations in anticipation of the US declaration of war on Germany. After several months of guard duty, the 9th was federalized and re-designated as the 101st Infantry Regiment, part of the 26th Infantry Division, an National Guard organization created from the units of the New England states. Logan accompanied his troops to France in command of the 101st, and the regiment saw combat throughout the war.
