Perhaps a little review of Greek history would tell you about the Battle of Thermopylae. There are hundreds of battles across the world and throughout history were smaller forces not just beat but routed much larger ones.
Trapping a larger force and immobilizing it through its own numbers is a common military tactic. It was commonly done by the Confederate generals who almost always faced larger forces. Those larger numbers mattered not until controlled by a man capable of using them effectively.
You really need to learn about such matters if you intend to discuss them.
I agree with you 100% on this. Lee and Jackson were master tacticians, and used smaller numbers quite effectively.
The Flank March at Chancellorsville, is STILL considered brilliant.
Your little sneer almost makes it seem like your comments should be related, or at least supportive of each other.
That smaller forces can prevail does not mean that is the rule. In fact, it is the exception to the norm.
