The King Stephen Báthory 81st Grodno Rifle Regiment (Polish: 81 Pułk Strzelców Grodzieńskich im. Króla Stefana Batorego, abbreviated as 81 pp) was an infantry unit of the Self-Defence of Lithuania and Belarus and the Polish Armed Forces.
The regiment traces its origins to the military formations of the Grodno Land Self-Defense, established on 12 November 1918. During the 1920 war, as the Grodno Rifle Regiment, it was part of the 1st Lithuanian–Belarusian Division. It fought against Soviet and Lithuanian forces, including at Stolovichy, Bobruisk, in the Republic of Central Lithuania, and participated in the Battle of Warsaw and the defense of Suwałki. After the reorganization of the Polish Armed Forces, it joined the 29th Infantry Division. Before 1939, it was stationed in the .
In the September Campaign of 1939, the regiment fought within its parent division as part of the reserve Prussian Army. Due to command errors, it operated detached from the main forces. Its combat path ran from Bartkowice Mokre forest through Trzebiatów, Brzuza, Wólka Kuligowska, and Kraszków to Przysucha forest, where, on 12 September, it was overwhelmed and destroyed by superior enemy forces.
In the Grodno Land Self-Defense The regiment's founding date is considered 12 November 1918, when the Grodno Land Self-Defense was established. Volunteers began joining the newly formed regiment from 14 command posts around Grodno. Officers were recruited from the former Russian army and the Eastern Corps, while enlisted men were exclusively volunteers from the Grodno region.
Uniforms consisted of both German and Russian attire, with some soldiers wearing civilian clothes. The distinguishing mark of Grodno units was a white-and-red armband bearing the seal of the Regency Council. Initial armament – 500 rifles with ammunition – was obtained from the Germans under an agreement with the Ober-Ost command.
Shortages in arms and equipment, coupled with German reluctance, forced Polish authorities to send some volunteers to Łapy. The unit's total strength reached 700 soldiers, including 30 cavalrymen, and was named the 1st Grodno Rifle Regiment. Major Jan Jackiewicz was appointed commander, with Major Bronisław Bohaterewicz leading the 1st Battalion.
By 10 January 1919, the formed and trained subunits were concentrated in . Major Bohaterewicz divided the 1st Battalion into three companies: 1st under Second Lieutenant Oreluk, 2nd under Second Lieutenant Romanowski, and 3rd under Second Lieutenant Piotr Daniszewski. A cavalry detachment under Lieutenant Czuczełowicz and a supply unit were also formed.
The unit's rapid growth alarmed the Germans, who decided to disarm the battalion in Kapciouka. On the night of 15–16 January 1919, German infantry surrounded the barracks. After arresting Polish negotiators, they forced the Grodno rifles to partially disperse and disarm. Only Lieutenant Czuczełowicz's cavalry escaped encirclement. On 23 January, Major Jackiewicz was arrested.
Some subunits regrouped near Grodno, where Major Bohaterewicz took command and reconstituted the 1st Battalion under Captain Waśkiewicz. On 4 February 1919, this battalion swore a solemn oath. Colonel Adam Dulewicz was appointed the new commander of the Grodno Land Self-Defense and negotiated a new agreement with the Germans, relocating the regiment to Krynki.
Within the 1st Lithuanian–Belarusian Division The next phase of reorganization began with an order from General Wacław Iwaszkiewicz-Rudoszański to establish the staff of the Grodno Rifle Regiment within the 1st Lithuanian–Belarusian Division. Colonel Franciszek Ostrowski organized it in Vawkavysk at the division's reserve center, with Lieutenant Colonel Stanisław Kowalski as deputy commander and Lieutenant Jerzy Dąbrowski as adjutant. The self-defense regiment was to become a fully-fledged unit of the reviving Polish Armed Forces.
The first subunit to join the division was Lieutenant Czuczełowicz's half-squadron of Grodno Uhlans, comprising three officers and 52 cavalrymen. On 7 March, Major Bohaterewicz brought the self-defense infantry to Vawkavysk, transferring command to Colonel Ostrowski. At this point, the regiment numbered 17 officers and 250 enlisted men. The 1st Battalion of the Grodno Rifle Regiment was formed under Major Bohaterewicz, alongside a non-commissioned officer school led by Captain Waśkiewicz.
The 2nd Battalion was established by late May from the division's reserve battalion in Vawkavysk. Like the 1st Battalion, it consisted entirely of volunteers from the borderlands. The 3rd Battalion was formed last, joining the regiment in June 1920. It was created from the reserve battalion of the 12th Infantry Regiment from Wadowice. According to Janusz Odziemkowski, the 3rd Battalion was originally the Mobile Mounted Rifle Detachment of Second Lieutenant Stefan Felsztyński, which relinquished its horses and reformed into two infantry companies.
In December 1919, the regiment's reserve battalion was stationed in Baranavichy.

1919 campaign The first subunit of the Grodno Regiment to engage in combat was the half-squadron of Grodno Uhlans under Lieutenant Stanisław Czuczełowicz, tasked with reconnaissance duties. On the night of 9–10 March 1919, this unit participated in an operation to expel Soviet forces that had temporarily occupied Slonim.
On 19 March 1919, the Grodno Rifle Regiment arrived in Slonim by transport, beginning its frontline service. It occupied a sector along the Shchara river from Mironim to Żyrowice. While conducting patrols, the regiment trained and reinforced its ranks.
In the operation to capture Vilnius, the regiment operated within Colonel group, tasked first with seizing Baranavichy. The battle for Baranavichy began on 15 April. Unable to take the town directly, on 17 April, a "northern group" was formed under Colonel Ostrowski to outflank from the north and strike the Soviet northern flank. This group included the Grodno Regiment (minus its 1st Company), the 3rd and 6th Companies of the Białystok Regiment, the 8th People's Militia Battalion, and a section of the 7th Field Artillery Regiment. On 19 April, after a day-long battle with the Soviet , the Grodno Regiment captured Stolovichy, suffering three killed and seven wounded, capturing 40 prisoners, and seizing four machine guns, seven horses, and significant amounts of ammunition and equipment. The action at Stolovichy is considered the regiment's baptism of fire as a cohesive fighting unit.
On 4 November, subunits of the regiment participated in the battle for Lyepyel, capturing it and successfully defending it against attacks by the Soviet 52nd Rifle Division. The regiment lost over 20% of its personnel in these engagements, with some companies reduced to about 40 men. During the winter, the regiment was reorganized: the 3rd Battalion was disbanded, and its personnel were used to reinforce the remaining subunits. The monotony of the winter campaign was broken by frequent raids on enemy positions.
In Żeligowski's group in the Republic of Central Lithuania Still part of the 1st Lithuanian–Belarusian Division, the regiment participated in Żeligowski's Mutiny. On 7 October 1920, it began its march "on Vilnius". Leading the 2nd Brigade, it advanced toward Wielka Czernica–Kudonino, capturing Ogrodniki in a direct assault. After seizing Vilnius, it secured the city from the north.
Combat summary From 1918 to 1920, 196 officers and enlisted men were killed in combat. Additionally, 90 died on the front. Numerical records indicate losses of 260 killed, about 800 wounded, and approximately 300 missing.
