 The 10th Motorized Cavalry Brigade's commanding officer was Colonel Stanisław Maczek, and his chief of staff was Major Franciszek Skibiński.Though the Brigade was fully motorized, it was still officially called the "10th Cavalry Brigade"; however, most print sources refer to it as "Motorized" to distinguish it from its predecessor.During the Invasion of Poland in September 1939, the brigade was attached to the Kraków Army defending Lesser Poland and Silesia.
