After days of research I have come up with almost nothing. Very little has been written about this phase of the war, At least in English.
I do know that 6 major battles were fought in Kurland and the German's stopped the Russians every time. Also Hitler forbade any retreat from Kurland or after the encirclement a break out attempt. Kurland held out till the German surrender. 220,000 German and Baltic forces were captured. 5th SS wiking fought in the area.
So the only option from here it seems is to purchase a book.
