Was this even really a good idea or did Caesar just get lucky?

It's a pretty good idea if you're a group like the Romans that

>is very good at military engineering
>has superior logistics to the enemy and can therefore wait longer
>keeps getting into protracted wars of aggression against barbarians

Its also a pretty good idea if you wanted to make a meme to last 2 millennia

It was a good idea against people who have little idea of siege warfare.

Ceasar tried the same with Pompey at Dyrrachium and it ended with a disaster.

good idea for roman way of fighting and caesar probably one of the luckiest commanders in history
