In A. Bata's book „Bieszczady in flames” there is a copy of the 'Report' of the County militia MO Headquarters in Lesko of April 2, 1947 with the following content:
„On 1.4.1947 in the afternoon hours 31 soldiers, including 6 officers and Corporal Duplak Jan, head of MO militia station in Cisna, were travelling from Cisna village to Baligród in a car. Around 1 pm at 5‑6 km from Baligród, the car was attacked and shot at by the overwhelming Banderite force, and the chauffeur of that car was killed.
As the driver was killed, the car was out of control and fell into a ditch. The soldiers, seeing that they had been attacked in an ambush by the Banderites, took up defensive positions in the ditches next to the road and defended themselves. About 150 Banderites for c. 30 minutes sprayed them with machine–gun fire and killed 20 soldiers, including Corporal Duplak Jan, head of MO militia station in Cisna, and wounded two soldiers.
Only one soldier of the Polish Armed Forces unit being attacked escaped to Baligród and notified about the accident. After arriving at the scene of the accident, it was found that 19 soldiers and head of MO militia station in Cisna were dead and 8 soldiers went missing without a trace, they were probably abducted by the attackers because they have not returned to their unit so far.
The injured were taken to hospital in Sanok. After killing the soldiers, the Banderites robbed them of their clothes and then, in a brutal way, stabbed the corpses with bayonets and broke their hands, and took all the weapons that the soldiers had. Expecting backup of other Polish Army soldiers they withdrew in an unknown direction.
After a short time, 70 soldiers arrived and took the dead and wounded to Baligród”.
The report was prepared by: handwritten signature — probable name: Kopiczyński.

J. Jastrzębski writes:
„On April 1, seven officers from the Border Protection WOP maneuvering group in Cisna went to Baligród on business matters. Duplak, who had been planning to go to the County Headquarters in Lesko for a long time, started with them. They traveled with the security of 24 soldiers armed with erkaems and automatic machines. In Jabłonki they got out of their cars and continued on foot. This is how they came to Bystry.
They were convinced that the most dangerous stage was over. They barely had time to get into the car and drive a few hundred meters, they were buried in Banderites' fire. Several soldiers were killed at once. The others fiercely defended themselves, but did not stand a chance against the overwhelming numbers and fire force of the Bandera followers.
When the tragedy site was reached by the help from Baligród — sent there when sounds of shots reached it — the bodies of 16 soldiers and officers, stripped naked and horribly mutilated, were lying on the road and in the nearby ditches. The seventeenth was Jan Duplak, massacred to a degree beyond human imagination. 10 soldiers were probably kidnapped and murdered by the gang, as they were lost without a trace.
The gang disappeared in the backwoods, although the pursuit immediately attempted to follow it”.

A colleague of the policeman Jan Duplak tells about this ambush, and his memoirs entitled „Only One Survivor” were published by Maja Bilska in the book „Ognie nad Solinką”:
„I will tell you now how my friend Duplak died in Jabłonka. He insisted on going with a group of 31 soldiers to Baligród  […] Only one soldier survived then, and returned after a few days in a cloak literally chopped up with bullets, barely alive from exhaustion. We learned about the fate of the rest from him. Duplak was in command of a militia unit at that time, and he also very much believed in his combat experience at the front. But he knew little about fighting gangs. Leading the unit, he confidently set out to penetrate the area and collect the contingent” (emphasis S.Ż.).
A Ukrainian, stopped on the way, informed the officer that in Kołonice, where he allegedly came from, there had not been a single 'partisan' for several days. In fact, when they entered Kołonice, apart from a few women, they did not even find any children. The village looked almost extinct. The soldiers, not seeing the threat, at the command of the commander, went to the pens.
„I was standing at the post closer to the forest and suddenly I saw that armed civilians appeared among the cottages  […] The whole clash lasted only a few minutes and ended in a complete defeat of the unit”.

„In the middle of this month (March 1947 – note by S.Ż.), one company of 34th Infantry Regiment was sent from Baligród to Smolnik. It was supposed to take the road to Cisna, connect with the Border Protection WOP Maneuver Group there and continue the march to Smolnik, along the forest railway route, through Żubracze, Maniów and Wola Michowa  […] ] You could also get to Smolnik by another road, half as long, but it led through Chryszczata. The company commander, against the orders received, decided to take shortcut  […]
'Ren' realized that the enemy was getting himself into an ambush  […] Sotnya 'Bir', located at that time in the area of Cisna, began a strenuous march towards Wołosań, the sotnya of 'Stach' took up positions on the slopes of Krąglica, and 'Hryń' outflanked the company from the north. In this way, the cauldron was closed, the combined forces of the Banderites numbered about 600 people and had almost five times advantage over the soldiers  […]
The next morning, the captured soldiers were led to the edge of the clearing. They were barefoot, without uniforms, in underwear only, traces of torture visible on their bodies. Everyone was murdered, only a dozen or so soldiers from the entire company encircled by Smolnik were saved” — writes A. Bata in the book „Bieszczady in flames”.

The same Fedir Kucyj (Stołyca), 'Prut', in a sound recording stored in the archives in Kiev  […] informs that the SB‑OUN clerk 'Mars' aka 'Bukowy' was very dissatisfied with the murder of commandant Duplak by the 'Bir' sotnnya, because „from that moment on, he no longer received copies of complaints and denunciations made by the Lemkos and Boykos against the UPA gangs”.
