To the Green Fields Beyond is a game created in 1978 by SPI, or Simulations Publications Incorporated. It is about the battle of Cambrai, which took place from November 20 to December 7, 1917. At Cambrai, the British and the French tried to use the newly invented tank (land ship as it was called at the time) to break through German front lines.
It won the Charles S. Roberts Award for "Best 20th century Game" in 1978.
The phrase Through mud and blood to the green fields beyond was the unofficial motto of the Tank Corps and From mud, through blood, to the green fields beyond is used as a slogan by the Royal Tank Regiment.
