German 4. Pancer Army - From which book comes this description?

[eagle100]

Hi,
on this website:

http://www.kunefke.de/index.php/abwe...sgefechte.html

we can find an interesting description of russian winter offensive in January 1945 from Baranow-Sandomierz (Poland) bridgehead against german 4. Panzer Army. There are two chapters: "5. RUSSISCHES NEUJAHR AN DER WEICHSEL" and "LANGER MARSCHHEIMWÄRTS".

Maybe someone knows from which book comes this fragment? What is the title and an author? I will be grateful for any help.

Best regards - Eagle.
