found this newspaper clipping about a successful Tiger Abteilung in the Witebsk area, newspaper is "Velberter Zeitung" from 13.3.1944, text from D.N.B. on 12.3.1944:
In short:
It's about a "schlesische Tiger-Abteilung", which since Dezember 1943 destroyed 275 tanks and assault guns plus 170 guns. In February 1944 alone this Abteilung destroyed 132 tanks and assault guns south-east of Witebsk. Main focus of the fights was the Nowiki bridgehead (here: Wowiki).
Once, 60 sowjet tanks with infantry attacked the German positions on the Lutschessa river, within 30 min. the 3 Tigers there shot 29 tanks: a Oberleutnant = 9, a Feldwebel = 12 and a Unteroffizier = 8.
Later the bridge over the Lutschessa river was destroyed by sowjet artillery, so 8 of the Tigers on the east bank where cut off from their supply. These Tigers again destroyed a lot of sowjet tanks in close quarter combat, also claiming high losses for the sowjet infantry.
Afterwards supply of fuel and ammunition was brought over the ice of the Lutschessa by foot.
A few days before this article, sowjet troops took about 600 metres of trenches to the west of the Lutschessa river. 3 of the Tigers together with Pioneer troops with flame throwers counterattacked successfully, they claim 500 sowjet dead.
4 Tigers to the southeast of Witebsk where attacked during the night by sowjet close combat troops, but they were driven back. In the morning one of those Tigers was hit by A/T fire and was towed backwards by another Tiger. The remaining two Tigers continued to fight back the attacking sowjet infantry. The damaged Tiger was repaired quickly and all 4 Tigers counterattacked, destroying the A/T guns and claming high losses to the sowjet infantry.
This unit is s.Pz.Abt. 501 which from December 1943 onwards was deployed on the Eastern Front. I have no idea as to the names of the three Tiger commanders mentioned, unfortunately.
If anybody can add some facts from the German or Russian side to these events I would be glad to see it
