1st Legions Infantry Regiment

First Legions Infantry Regiment of Józef Piłsudski (Polish: 1 Pulk Piechoty Legionow Jozefa Pilsudskiego; 1 pp Leg.)

A few months later it joined fighting against the Red Army: in the area of Wilno and in eastern Polish territories (present-day Belarus).

After a Soviet counteroffensive, the regiment, together with other Polish units had to retreat, fighting the Russian 1st Cavalry Army of Semyon Budyonny.

On December 3, 1920, Marshall Józef Piłsudski decorated the flag of the regiment with Silver Cross of the Virtuti Militari.

In 1930, Polish Ministry of Military Affairs included the regiment into the Second Category, which meant that in case of armed conflict, it was to be mobilized as one of the first units.

In late August 1939 the regiment, commanded by Colonel Kazimierz Burczak, was concentrated in forests between the Bug River and the Narew, as part of 1st Legions Infantry Division (General Wincenty Kowalski), Operational Group Wyszków.
