Any good online sources about medieval field fortifications? Not a castle or established fort, but something closer to ww1 trenches, though not necessarily trenches.

Structure relatively "quick" to make that you would not care about leaving behind like how trenches would be abandoned as your side was able to advance. I would say seige camps, but those often turn into pure forts with literal food markets over time so they dont count.

I am not too worried timeline wise, early renaissance is fine too.

I am not too fussed about how the information is presented, be it book, article, or video.

All these links are about wagon forts which are pretty cool. They did dig burns and place sharpened sticks to combat cavalry too but I used ai to help me find source websites and it decided to focus only on the wagon forts
