Iphikrates did that minus the cavalry in the Corinthian War. He almost wiped out a Spartan hoplite battalion (600 men) with peltasts alone. Those few who escaped the peltasts were killed by Athenian hoplites I think.
Will come back when I find which battle and sources.

The battle/skirmish was near Korinthos in 390...I believe the proper name of the battle is Lechaion. He basically destroyed an unsupported Spartan hoplite mora with rearmed hoplites, which by that time had gotten considerably lighter.

There is also an ocasion where Spartan hoplites surrendered after being hit by Athenian archers for a couple of days.

And infierno, that's all fantasy...there are other more practical ways of defeating a heavy-phalanx army than going Ewok on them. AS you can see, archers and javelineers do just fine, simply by being able to outrun and outrange them.

EDIT: CBR: Double handers were used by Swiss mercenaries since the 14th century and although outlawed in some cantons, they were still exported to other countries who used them well into the 16th century. Two centuries is not a small time to use such a speacialized weapon.
