LT2013 m. birželio 20-rugpjūčio 4 d. KšM archeologinė ekspedicija tyrinėjo Lietuvos partizanų Didžiosios Kovos rinktinės Ignoto Nasutavičiaus Bondaro būrio bunkerį Pagrendos miške (Elektrėnų sav., Pastrėvio sen.). Bunkeris yra Pagrendos miško ŠV dalyje, 61-ojo kvartalo 9-ajame sklype. Archeologinių tyrimų metu aptikti radiniai perduoti saugoti KšM, dalis jų restauruota VDKM Restauravimo skyriuje. Pagrendos miško partizanų bunkerio istorija siekia ankstyvąjį partizaninio karo laikotarpį. I. Nasutavičiaus vadovaujami laisvės kovotojai 1944 m. rudenį miške prie namų įrengė 3 bunkerius. Vienas iš jų 1945 m. sausio 20 d. buvo išduotas ir užpultas. Apibendrinant reikia pasakyti, kad archeologinių tyrimų metu buvo aptiktas lenktas bunkerio įėjimas ir medinės konstrukcijos, nustatytas jų dydis, patikslinti istoriniai duomenys ir atkurta bunkerio šturmo eiga. Pagrendos miško bunkerio archeologinė ekspedicija tapo pirmąja, kuri ne tik ištyrė partizanų bunkerio vietą, bet ir remdamasi tyrimų rezultatais ją sutvarkė: atkūrė iki tyrimų buvusį bunkerio duobės vaizdą, suformavo tikslius bunkerio ir jo įėjimo kontūrus.

ENIn 2013, a KšM archaeological expedition excavated the platoon bunker of Ignotas Nasutavičius-Bondaras of the Didžioji Kova brigade of the Lithuanian partisans in Pagrenda forest (Elektrėnai municipality). The bunker was created in the autumn of 1944, betrayed, and attacked on 20 January 1945. During the Chekist military operation, four partisans died and one or two successfully escaped the bunker. During the investigation, 28.8 m2 were excavated and an area stretching 30 m from the bunker were surveyed with a metal detector. The bunker’s curved entrance and wooden structures were discovered. It was discovered that the bunker had been 3.4x2.6x1.5 m, the entrance about 60 cm wide. 14–15 cm diameter fir ceiling joists (the longest being 3.3 m long) were discovered in the bunker’s walls. The walls were made of undisturbed clay loam and clay; no wooden structures were used to reinforce the walls. A 4–5 cm thick base of dark grey clay was recorded at the level of the bunker’s floor, a distinct layer of burnt straw at the entrance location.A total of more than 700 finds were discovered during the investigation. The bulk of them consisted of ammunition: german and russian cartridge casings and bullets. A german kampfpistole, at least four hand grenade fragments and an unexploded F1 hand grenade in the bunker’s vicinity, a german uniform button, a small rosary fragment, nails, and glass shards were discovered The investigation results reveal that a fierce battle took place in Pagrenda forest. After an analysis of the munitions and hand grenade fragments has been made, the course of the assault on the bunker can likely be recreated. The expedition corrected the historical data, presented a new, more comprehensive narrative of the bunker’s history, and contributed to the development of modern age conflict archaeology in Lithuania.
