2 July - Northern Gate captured
4 July - Eastern Fort cleared (about 20 remaining defenders killed)
12 July - Breakthrough of Major Gavrilov group (Major was wounded during breakthrough and hided in ruins and was captured after a short fight only 23 July!)
14 July - Pioneer Barracks captured – ( 7 remaining defenders killed)
15 July - unknown soldier jumped out of the upper section of Terespol Gate with pack of grenades on a passing by column of german soldiers
The information I have as narrated in Will Fowler's Barbarossa: The First 7 Days on page 133 is that Major Gavrilov surrendered with 388 men in the citadel on June 29. I would like to know what sources the museum at Brest, Belarus, uses to establish the claim that Gavrilov was captured on 23 July.
Since the defenders you note all died and not captured or interrogated, what sources are there that they resisted until those dates. What corroborating evidence is there that the claims of the Belarus government are indeed accurate?
Who if anyone has authenticated the writings of soldiers within the walls of the citadel? Were they discovered by the Germans in 1941? Or were they discovered by the Soviets in 1944? Were these scratchings covered by rubble or in the open? What I question is that why would Soviet soldiers write on the walls while they were not yet discovered by the Germans and thus present to the Germans the fact that the soldiers were still alive and resisting within the fortress.
