Where to start with this conflict?
I’ve read enough on the topic both old and new – S&T 33’s take on this battle, as well as more recent writings using new archival data in a book called The War of the White Death, to do a bit of brain dump. However I think nearly everyone has a good handle on the situation and the result!
All good stuff. The bottom line is we face a situation not unlike that of the Prussians fighting @ Jena in 1806. Where the Prussian Army fought a conventional (for then) battle. While the French brought their innovations in Corps structure, maneuver warfare and encirclement to bear upon the Prussian forces, who were summarily crushed.
The here Russians fought a WWI style conflict, of massed arms, and bloody frontal assaults. While the Finns through need and lack of resources fought a more modern style of battle. The result is different but the dichotomy of approach is the similar.
