Its traditions were continued during World War II, by a regiment of the same name, which was part of Polish Armed Forces in the West.

During the Polish–Soviet War, the regiment fought mostly in Volhynia, engaging in a number of battles and skirmishes against 1st Cavalry Army of Semyon Budyonny.

After the war, in spring 1921, it occupied former barracks of Imperial Russian Army in northern town of Augustów, where it remained until 1939.

In the second half of 1941, the regiment was recreated as part of Polish Armed Forces in the East, the so-called Anders' Army.

In December 1914, during early months of World War I, Russian authorities announced the creation of two volunteer cavalry squadrons, as part of the so-called Puławy Legion.

The uhlans moved in to protect its civilian population, and five days later they fought German units in the Battle of Krechowce.

The regiment was dissolved in May 1918, but in October of that year, the Regency Council ordered creation of additional units of the newly created Polish Army.

In early December 1918, all subunits of the regiment concentrated in Tarnow, in order to march eastwards, and help Polish defenders of the city of Lwów, which was threatened by Ukrainian forces (see Battle of Lemberg (1918)).

On 17 December the soldiers went by train to Przemyśl, and all throughout winter of 1918/1919, the uhlans fought in the area of Lwów, mainly in Gródek Jagielloński.

Meanwhile, its flag had been brought from Bobrujsk, and on 7 May 1919, the regiment left Wolbrom again, towards Volhynia, where Polish offensive began (see Polish–Ukrainian War).

The regiment, with its quick movement, took the Ukrainians by surprise, capturing the city of Lutsk, together with 600 prisoners, cannons, vehicles and food.

After a few weeks' march via Chełmża, Popowo Biskupie, Grudziądz, Nowe, Pelplin and Żukowo the uhlans reached Puck, where on 10 February 1920, Poland's Wedding to the Sea took place, with General Józef Haller present.

Its task was to capture the town of Koziatyn, with its important rail station and Red Army supply depot.

In two days, Polish cavalry, with 20 officers, 600 soldiers and 10 machine guns, crossed 160 kilometers (see Battle of Koziatyn).

Until 8 August it fought along the Styr River, but due to numerical superiority of the enemy, it was forced to retreat to Radziechów.

On 24 July 1932, it celebrated its 15th anniversary, with President Ignacy Mościcki, and a number of high-ranking military officials, such as Edward Smigly-Rydz, Tadeusz Kutrzeba, Juliusz Rómmel and Stanisław Grzmot-Skotnicki.

The legendary horse had its own, separate stable, and after its death in 1939, Krechowiak was handed to Polish Army Museum in Warsaw, where it was stuffed and presented to visitors.

First enemy assault was repelled, but in subsequent attacks, Colonel Jan Litewski, commandant of the regiment, was killed and his post was taken temporarily by Rittmeister Tomasz Mineyko, who ordered a withdrawal.

Near the village of Kamien, Polish soldiers halted the enemy, destroying 10 tanks and capturing a number of prisoners.

In the night, after a quick march, the uhlans reached the road Wysokie Mazowieckie - Brańsk, crossing the Mien river after a bloody skirmish with the enemy.

The Germans lost 20 tanks and armored carriers, but Polish losses also were very heavy and the regiment dispersed, as some of its subunits decided to march to Wołkowysk on their own.

On 24 September, the 1st Regiment, which was part of Brigade Edward, Zaza Cavalry Division (named after General Zygmunt Podhorski) crossed the Bug River near Niemirow and kept marching southwards.

Fighting its way against Soviet and German units, the uhlans hoped to eventually reach the Hungarian border, located hundreds of kilometers south.

In the Battle of Kock (1939), 1st Krechowce Uhlan Regiment was stationed near Józefów, and tasked with attacking left wing of German positions.
