the ground is level.

If the ground slopes, the cavalry charging downhill will be multiplied
according to the number of contours crossed. If it is one contour, it
must be multiplied by two; two contours, multiplied by three; three
contours, multiplied by four.

If cavalry retires before cavalry instead of accepting a charge, it must
continue to retire so long as it is pursued--the pursuers can only be
arrested by fresh cavalry or by infantry or artillery fire.

If driven off the field or into an unfordable river, the retreating
body is destroyed.

If infantry find hostile cavalry within charging distance at the end
of the enemy's move, and this infantry retires and yet is still within
charging distance, it will receive double losses if in extended order if
charged; and if in two ranks or in fours, will lose at three feet two
men for each charging sabre; at two feet, three men for each charging
sabre. The cavalry in these circumstances will lose nothing. The
infantry will have to continue to retire until their tormentors have
exterminated them or been driven off by someone else.

If cavalry charges artillery and is not dealt with by other forces, one
gun is captured with a loss to the cavalry of four men per gun for a
charge at three feet, three men at two feet, and one man at one foot.

If artillery retires before cavalry when cavalry is within charging
distance, it must continue to retire so long as the cavalry pursues.
