During the Polish-Soviet War of 1920 the city of Lwów (modern Lviv, Ukraine) was attacked by the forces of Alexander Ilyich Yegorov. Since mid-June 1920 the 1st Cavalry Army of Semyon Budyonny was trying to reach the city from the north and east. At the same time Lwów was preparing its defenses. The inhabitants raised and fully equipped three regiments of infantry and two regiments of cavalry as well as constructed defensive lines. The city was defended by an equivalent of three Polish divisions aided by one Ukrainian infantry division. Finally after almost a month of heavy fighting on August 16 the Red Army crossed the Southern Bug River and, reinforced by additional 8 divisions of the Red Cossacks, started an assault on the city. The fighting occurred with heavy casualties on both sides, but after three days the assault was halted and the Red Army retreated. With the crushing defeat of the main forces of the Red Army in the battle of Warsaw, and the Polish victories at Komarów and Zadwórze, the Russian forces were forced to retreat from Lwów.

Budyonny's insistence (bordering on insubordination) on capturing Lwów has led to weakening Soviet forces near Warsaw and was a factor in their eventual defeat. The battle Around the time of Battle of Radzymin in mid-August, the Polish line of defense in the upper Bug River region had been breached by the Red Army. Polish units in that region had begun a series of delaying maneuvers (like the battle of Zadwórze) and retreated towards Lwów. Polish 1st Cavalry Division engaged Soviet units under Budyonny near Artasowo and Żółtańce. On 12 Aug., Budyonny received orders for the Konarmiya "to destroy the enemy on the right bank of the Bug in the shortest possible time and, having forced the river, to follow on the heels of retreating Third and Sixth Polish Armies and seize the city of Lwow."
