The group finished the Battle of Friedland last night. The Russians held onto the town of Friedland to earn a draw. Bagration's wing was completely destroyed, but the 1st (Guards) Division, the remnants of the 14th Division, and the late-arriving Flying Corps under Platov managed to hold off a furious push by Ney's Corps.
Losses from the third and final session:
5 artillery batteries
14 artillery batteries
And total losses from all three sessions of the Battle of Friedland:
9 artillery batteries
26 artillery batteries
Lannes' Reserve Corps and Grouchy's Cavalry Corps were severely mauled. Bagration's wing was annihilated. The other Russian wing was also pretty beat-up, but the French could not exploit the situation to drive into Friedland before the dark of night.
I'll upload some pictures of the final dispositions of the troops tomorrow.
