I have a few questions on it just so I can understand it more, because I don't really understand it.

1. How long would storming a Trench take?

2. If an offensive took and held 1 Trench deep on the other sides lines, how would that affect the rest of the front and trenches near it?

3. Was there just 1 large Trench line across the whole western front?

4. How did they divide the sectors? Like when one Trench raided another, where did they decide the attack to cut off so its neighbours don't attack, was there sectors?

5. I read a book where it said the pashendaele battle took months. How did that work? Was there troops going over the top 24/7? When did they sleep? Also was Pashendaele Trench warfare like the Somme or was it more hectic like the movies.

Sorry about the amount of questions, if you have any other facts about trenches feel free to share I want to learn as much as I can!
