G.H.Q. was made in 1939 and released either that year or in 1940. It was then almost immediately removed from the market as the German Wehrmacht had started their attack on France.
The game is a strategic war game for two players, one player representing the Allied Armies and the other the German Army. The theater of War is the Western Front and the territories of countries adjacent to that front. The Object is to occupy ONE of two capital cities of the opponent.
On the map, the towns are shown as red circles and connected together by thick red lines which represent the road and railway systems. Towns with black centers are Corps garrison towns and the associated units are marked on the map. The units (armored, motorized, and infantry corp) are represented by differently shaped wooden pieces with Flags attached.
The Germans always go first and movement is governed by a roll of the dice. The roll will be between 1 and 3 and the number thrown indicates the number of units that may be moved. Armored corps can move 3 spaces, Motorized 2 and Infantry 1 space. Destruction of units is based on having units adjacent to the target enemy, 3 friendly units are required to kill an armored unit, infantry and motorized are destroyed by two friendly units in adjacent towns. For every enemy unit destroyed the player gets another roll.
