The Volhynian Cavalry Brigade () was a Polish cavalry brigade, which saw action against the invading Germans during the Invasion of Poland, a part of World War II. Raised from recruits in the area of Wołyń, the division was posted to the Łódź Army. During several desperate counter-attacks, the brigade suffered heavy casualties near Łódź. It was commanded by Colonel Julian Filipowicz. Most notably, the unit took part in one of the first battles of the German invasion of Poland (and thus, World War II), the battle of Mokra. History The Vohlynian Cavalry Brigade was formed on April 1, 1937, out of sub-units of the Równe Cavalry Brigade, and several smaller detachments. Formed out of recruits from the region of Volhynia, the brigade was decentralized and its units stationed in several towns from the region, including Równe, Dubno, Białokrynica and Ostróg by the Horyń. As part of the first wave of the Polish Army, the brigade was fully mobilized prior to the outbreak of World War II, and transported to the area of Łódź. In accordance with the Polish mobilization scheme, the brigade was attached to Wiktor Thommées, Piotrków Operational Group, of the Łódź Army. The brigade was to form that unit's mobile reserve and cover the planned retreat of the 7th Infantry Division. After the beginning of the Invasion of Poland on September 1, 1939, the unit took part in the battle of Mokra, where it held its ground although with heavy losses. The brigade withdrew towards the east, and the following day defended the second line of defense near Ostrowy, where it suffered further casualties. On 2 Sept., the brigade held up the 4th Panzer Division (Wehrmacht). On September 3, it reached the main line of defense of the Army along the Warta-Widawka line (Łękińsko-Łękawa-Janów). With its flanks covered from both sides, the 2nd Mounted Rifles Regiment made a successful sortie towards the village of Kamieńsk, on September 4, where it surprised the German 4th Panzer Division, and destroyed several of its tanks and a dozen of its fuel tanks, killing approximately 100 enemy soldiers. The following day, the entire brigade took part in a sortie towards the village of Wola Krzysztoporska and Jeżów, but were forced back after a German counter-attack. On September 7, 1939, the German forces finally managed to break through the lines of the Łódź Army and the brigade was forced to retreat after
