OK, I've read several books about 26th, 27th and 28th days of April. I've picked out only description of the situation, without any description of soldeirs' feats etc.
So it's very edited version - only 2 pages of 12 font in Word, so I translated it as I had free time, however I'll send list of books from which I've taken this parts (links, to be exactly).
Berlin was in fire. The sky turned into yellow-brownish colour. Over roaring city, which was covered in ashes from fires, was floating dense cloud of black smoke and dust.
Goingforward. But barricades and heaps of rubble were blocking every tank’s and AT gun’s way. Sappers couldn’t get to this barricades as fascist were holding them under fire. However, Chujkov’s infantry helps us out: they smoke out bastards with flamethrowers.
We knew that German capital has subway, but in the heat of battle we either forgot about it, or just underestimated it from tactical point of view (reinforcements could arrive via underground passages). But this gave germans great chance to maneuver. Using subways, hitlerites could hit us in the rear.
Moabit prison
Gloomy mass of prison was silent. Huge 5-corner building seemed to be waiting our punch and was reading to hit us with all its secret power and anger. Its very thick walls weren’t afraid of bullets and rounds, there were no bars on the windows, every one of them became embrasure (sp? – fire port). It had good circle defense.
Huge iron gates stood out. In courtyard about ten buildings were rising above the massive brick wall.
Direct fire’s, tanks’ and even 122mm SPGs’ rounds could do nothing with its powerful walls. Every our maneuver hitlerites were meeting with fire storm.
Soon from through window of a house on Alt Moabit we saw truck towing a gun. It should stand to the right of kirche on open space in front of the prison, in 300-650 m distance.
After few minutes gun fired with heavy crash and the very first round took out a massive part of a wall. Artillery men fire round after round, German return-fire less and less, Germans are definitely in panic, and then our infantry breaks into the prison. Short fight – and Germans capitulate.
After taking the Moabit prison 1st battalion begun good advance on Alt Moabit’s street. But in short time – new obstacle – 5 story П-shaped building (it was Ministry of Finances). Its right side was looking at Alt Moabit. Hitlerites had a powerful supporting point here and had every approach to it under heavy fire.
After 15 min artillery fire 6th company swiftly broke into it had its garrison divided on 2 parts. In that very time 4th and 5th companies assaulted the building from different sides. Thebuildingwascompletelycleanby 18 PM. This let 1s tbattalion to try and cap the Moltke bridge.
Entrance to Moltke bridge was blocked by a wall 1.5m high and not less than a 1m thick. The other end had the same wall, all bridge had dragon teeth. All this – against our tanks. Try cleaning the way under fire…
