"During the combat in Gdansk (Oliwa and Wrzeszcz districts) and Sopot, SS-Untersturmführer Karl Brommann (commander of the 1st Company) destroyed 65 tanks and self-propelled guns along with 44 artillery pieces and 15 vehicles (including some T-34s from 1st Polish Tank Brigade "Heroes of the Westerplatte"). Following his outstanding score, Brommann was awarded with Knights Cross."
Schneider's Tigers in Combat II gives some more details of these actions:
"26 March 1945: Several attacks are repelled, and six Josef Stalin tanks are knocked out. One Josef Stalin, which was captured by Sturmgeschuetz-Brigade 190, is put under German command; when it becomes non-operational, it is finally sunk in the harbor."
Oliwa and the nearby suburb of Sopot are mentioned, pinning the location of the regiment pretty precisely. There is nothing about the total tank claims here, but at least we get some specifics: seven total lost IS-2 tanks on March 26th. Let's take a look at who these tanks could have belonged to.
- 922nd Self Propelled Artillery Regiment: no losses.
