Continuing from part 1…
On 5.9.1939, the Polish line of defense was broken and the unit became partially surrounded by the Germans. The 10th Cavalry Brigade fought series of battles with the Germans while retreating towards the Dunajec river in southern Poland and it was only on 7.9.1939, when the unit finally got some well-deserved rest after six-days of non-stop marching and fighting. The unit used the spare time to load up on ammunition and to consolidate the troops – the fuel, however, was a constant problem.
Colonel Maczek ordered the unit to move to Rzeszów to cover any access to Lwów (Lviv). However, the march proved to be catastrophic for the Polish cavalrymen, because they were forced – due to the lack of fuel – to abandon most of their armored vehicles, including their most potent weapons, the Vickers light tanks.
By the time the Germans crossed the river San, Maczek proposed a combined operation of his brigade and the Przemyśl armies to throw the Germans back and to destroy their bridgehead. This plan however was not accepted and the brigade recieved the order to cover the Lwów-Radymno direction – from there, the brigade was moved directly to Lwów to defend the city on 12.9.1939. Ironically, it was the second time Colonel Maczek was defending the city – previously, he participated in its defense against the Soviets in 1920, this time, he is about to fight the German invaders.
