Just for the record. 41 attacking nobles against 41 defending nobles.
Total:
41 attackers (1739 Inf, 602 Arch, 69 Cav, 399 SF)
41 defenders (794 Inf, 60 MI, 865 Arch, 274 Cav)
Total combat strengths: 33903 vs. 22695
As Indirik mentions, the north archers were deadly though. I guess the northern weather make the arrows much tougher and good quality in hunters archers.
