General Bołtuć, who was remembered positively by Bortnowski himself, was supposedly hot-tempered in both word and action. During the September Campaign, Bołtuć dismissed both commanders of the two divisions which were part of his Operational Group. It is alleged that as a result of the bombardment during the Battle of Bzura, as well as the break-through towards the Modlin Fortress, Bołtuć may have suffered from a nervous breakdown. Bołtuć attributed to Bortnowski the series of disastrous events of September 1939 which eventually resulted in Nazi Germany's and Soviet Russia's occupation of Poland. Specifically, Bołtuć criticized the "absurd" deployment of three large Polish Army units - the Pomeranian Cavalry Brigade, the 9th Infantry Division, and the 27th Infantry Division, into the Polish Corridor, which would allow Germany forces to cut Poland off from access to the Baltic Sea. Bołtuć was correct - General Günther von Kluge's 4th Army quickly utilized this tactical botch. Kluge and his 4th Army captured the Corridor by smashing through the three Polish units, and cut off the rest of Poland from the Baltic coast, where several Polish coastal defense units remained and were forced to defend alone, which resulted in the notable Battle of Hel.
