Thanks for clearing that - i had full spears routing especially in large team games just like that because i missed the ordered formation morale impact.
They fight longer in the presence of allied units because they may be getting a morale bonus from having their flanks covered, and they will have less outnumbered morale penalty as they would if operating alone. YS are not actually design to operate alone. Only the high morale units can sucessfully operate alone in the presence of many enemy units.

Morale 10 = WM, ND, BN
Morale 8 = Hatamoto, HC, NC, NI
Morale 6 = YC, CA, YS
Morale 4 = SA, YA
Morale 0 = JT, PT
