As Custer learned, never split your forces in the face of superior numbers. This usually applies to the party as well. But sometimes you can split the party to effect an ambush and win a fight without taking any casualties.
In D&D however since most characters are very specialized, it's usually a bad idea to split up since there are some things certain classes have no attack or defense for.
