Warsaw capitulated on 27 September, before Dobrzański and his men were able to reach it. That left him faced with three choices: disband, evacuate (via Hungary or Romania) to France, or continue the fight. Approximately 50 men volunteered to continue the fight. He led his unit southwards to try to break out and reach France. On 1 October 1939 they crossed the Vistula near Dęblin and started their march towards the Holy Cross Mountains. The same day his unit fought their first skirmish against the Germans. After that he decided to stay in the Kielce area with his unit and wait until the Allied relief came, which he expected in the Spring of 1940. He also swore that he would not take off his uniform until after the war. He named his force the "Separated Unit of the Polish Army" ("Oddział Wydzielony Wojska Polskiego"). On 6 October the Battle of Kock ended the resistance of the last major unit of the Polish Army. With the support of the local civilian population, Hubal and his men managed to evade the Germans.
