There are many maps in circulation that depict the battlefield during the Battle of Arnhem. Those cards show a snapshot of a specific moment during the fighting.
You Tube user S Rais made an interactive map several years ago that shows the course of the battle. The map runs from the airborne landings on Sunday, September 17 to the early morning of Thursday, September 21 1944.
There are a few small errors in the map, but the video below gives a good picture of the course of the battle.
