When God made the world he made the big plain just for the cavalry. It was firm, or would be when the sun had dried off the night's rain, and it was mostly level. The sabres could fall like scythes in the corn. The Arapiles, Greater and Lesser, God made for the gunners. From their summits, conveniently made flat so that the artillery could have a stable platform, the guns could dominate the plain. God had made nothing for the infantry, except a soil easily dug into graves, but the infantry were used to that.
