Looking at this battle specifically, I agree that Egyptian didn't violate any rules. It is a very small thing to overlook, but something you should keep in mind Adanedhel. If Isengard disbands the defeated units, he is allowed to sally (and so would anyone be in such a situation). However, if you besieged him while one of his generals was defeated, Ugluk or Saruman, then Isengard would not be able to sally (simply because the game engine wouldn't allow him to). I'm sure that the game engine wouldn't allow Egyptian to sally if he doesn't disband the defeated units.
Hence, a small thing to overlook, but all in line with the rules.
