Partially true; a WWI style 400 mile trench system is not feasible. We have already scene American Civil War style entrenchments as defensive works around a high value target with the besieging troops encircled by a second set of trenches.
Charisian artillery and a bit of helpful disinformation from one of Merlin's aliases, broke the entrenchments in short order, but equipped closer to parity -- a la union vs confederate -- such strong-point entrenchments could tie up armies for an entire fighting season.
