@darth ladnar You've explained your theory well. My counter argument is that the simple reason the Rebel's used the back entrance, as shown to them by the Ewoks is that it was an easier point of entry into the generator building. It was a good move since they did gain entry quite easily. However, & as I said earlier this becomes irrelevant when they are captured. The Imperials then have the option of taking them out through whichever entrance they like. Clearly the Imperials knew of the Rebel's movements since such a large force including the AT-ST's turned up so quickly after they entered the generator. I think focusing on the definition of the term "legion" & referencing history is a bit misguided. Star Wars films are simple movies with simple story telling. Palpatine tells the audience that a legion of troops are awaiting the Rebels. Cut to the next scene & a large number of troops, officers & AT-ST's are surrounding the Rebels - that's the legion. The Rebels are hugely outnumbered & all hope seems lost...then the Ewoks turn up. The point is that the Ewoks with their primitive technology could outfight the Imperials in their native environment. The point isn't that the Rebels were lucky enough to attack where most of the Imperials were cut off & couldn't get to the fight. Looking at that part of your theory for a moment. I agree that since we didn't see the AT-AT we can assume that it was either cut off or couldn't get through the dense forest to the battle. Btw I disagree that this was their most "effective" weapon. It was their most powerful but the AT-ST's were probably more effective given the terrain. Anyway, there is no good reason why troops, scouts & AT-ST's would be cut off by some trees. Your argument was that the majority of the "legion" was around on the front side of the generator building. However after the fighting began those troops & AT-ST's surely had plenty of time to get to the battle, even if the back entrance was a bit of a distance away. The troops could have even traveled through the generator building itself to the back entrance. Also, after the Imperials are defeated & Han coaxes out some troops stationed inside, the Rebels then casually stroll into the generator building & place explosives everywhere. Are you saying that while they were doing this there were hundreds or thousands of Imperial troops right outside the front door?? What is far safer to assume is that a smaller number of troops remained at the front entrance to guard it along with the AT-AT (although that may have stayed at the landing platform). The rest of the legion engaged the Rebels, which was the whole purpose behind Palpatine sending them there.
