The game begins with the British holding the area around the bridge, surrounded by the Germans. They try to hold out for as long as they can.
Each full turn covers 8 hours and includes many mini-turns (or impulses). Each impulse, the player can move or fire a small number units. Once moved or fired, the units are "committed" and cannot move or fire again until the next turn.
Combat is handled by calculating attack and defense values with each side adding the roll of 2 dice. The difference (if the attacker has the higher total) in final point values is the number of casualty points the defender must lose by retreating or destroying units.
The games is of relatively low complexity for a wargame and rates 3 (out of 10) on AH's difficulty scale.
A slightly updated version of my player aid for AH's 'Storm Over Arnhem' including several rules that I'd left out in the previous version and in PDF format this time. A bit larger than A5 and double-sided.
Rules for the folio ver. of the game. Only difference between this and the book shelf ver (that I know of) is the use of chits instead of d6's. I did not scan this, I am just posting to the best place I know of to keep these alive.
