1 - You're talking about an ARMY, not 3 guys with entrenching tools.
2 - Even with just an entrenching tool 1 guy can build a slit trench big enough for himself to hide in just over an hour (personal experience here, in rocky ground after forced marching 20km to the site). How big a trench with redoubt behind could several thousand build? If they couldn't build a fortification they would create abatis, which I don't care how big and strong the elephant is - it aint getting through!
4 - Do a Google search for 'ha-ha'
5 - We have archeological evidence here Phil! I think you'd be truly surprised at how quickly a fort could be built.
6 - Battles were usually fought after waiting for days for conditions to be right. Very rarely did they come right out swinging. There are several examples of various omens not being right for battle and/or (in the case of the Romans) personage X being in charge on day 1, and personage Y being in charge on day 2, so why give battle when personage 1 is in charge - wait until tomorrow!
