During the January Uprising the regiment was moved back to Poland and attached to the 2nd Brigade, 3rd Guards Infantry Division. The regiment remained there until the outbreak of World War I. It took part in the failed Russian invasion of East Prussia as part of the XXIII Army Corps, and then the inconclusive Battle of Łódź. In the summer of 1915 the regiment formed the core of General Vladimir Apollonovich Olokhov's ad-hoc Army Group unsuccessfully trying to cover the flanks of 3rd and 8th Armies during the Gorlice–Tarnów Offensive.
