Here are parts of memoirs of two Polish officers of 9th Mounted Rifles Regiment (Podolska Cav. Bde) from September Campaign. They both describe the same event or its aftermath - destruction of 3 German armoured cars.
2nd Lieutenant Czesław Hake, commissary officer
Jan Kaczorowski, since Sept. 6th head medical officer of regiment(...) From diary: Oszczepalin Pierwszy, 2.X.39r. - a plane flying low was seen yesterday. It was ours. We crossed a river. On the road 3 knocked-out armour cars. Massacre inside.(...)
(...) One of our wachmeisters told me a story about finishing-off of these hitlerite armoured vehicles. I don't remeber though which cavalry regiment did it. Our men were in a scrub, about 500 metres from the road. They had an AT gun and AT rifles. When enemy vehicles appeared on the distant horizon, the sharpshooters with AT rifles hid in the potatoe field. They were given the task to finish off the last vehicle. They were to start as soon as AT gun fired. The enemy was allowed to move to point where road passed near the scrub and the the AT gunner pulled the trigger.
The vehicle stopped after second shot. A few seconds later the second armour was pierced. In the same time uhlans coped with third armoured car that turned out to be radio. They hit the engine which burst into flames. Krauts bailed out and then our lmgs started its play.
All that lasted over a dozen seconds. Later it was found out, that two holes made by our projectiles in armour of first car were so close to each other that they could both be covered with a palm.(...)
Was it really official German delegation to Soviets? Who could have travelled in those armoured cars? What unit did they belong to?(...) After this incident the Brigade reached Kock, where following event took place on October 1st: mounted officers recon squad identified 3 German armour units on move towards Kock. 10th Uhlan Regiment, commanded by Lieutenant Colonel Busler, had set up an ambush and destroyed the enemy. Only 2 German mechanicians survived - wounded in the head. Interrogation and captured documents revealed, that this was Hitler's delegation sent from Breslau to Brest-Litvovsk to agree details of partition of Poland. A map found in vehicles had Curzon line drew in blue, which separated areas of German and Soviet influence over captured Polish territory. (...)
Any help would be appreciated.
