Movement Table (1912)

This table calculates the effect of elevation on movement.

Arm	Gait	Distance		Reduction for Slopes. In yards horizontally per ten feet vertically*	Maxim Slope Practicale
Arm	Gait	Yards per Minute	Miles Per hour		Deg.	Vert /Hor.
Infantry	March	88	3	Up: 10 Down: 10 for slope above 10 degree	45	1/1
	Double	147	5	Down: 10 Up: 20 for slope above 10 degree	10 20	1/6 1/3
	Advancing by rushes	16
	Advancing and firing	40
Cavalry	Walk	117	4	Up: 40 or slope above 5 degree Down: 60 for slope above 5 degree	25 20	1/2 1/3
	Trot	234	8	Up: Same as walk Down: Same as walk	15 10	1/4 1/6
	Gallop	352	12	Up: Same as walk Down: Same as walk for slope above 3 degree	10 5	1/6 1/12
	Charge	440	15	Up: Same as walk Down: Same as walk for slope above 2 degree	5 5	1/12 1/12
Artillery	Walk	117	4	Up: 10 Down: 60 for slope above 5 degree	10 10	1/6 1/6
	Trot	234	8	Up: 20 Down : 60 for slope above 3 degree	5 5	1/12 1/12
	Gallop	352	12	Up: 30 Down: 60 for slope above 2 degree	5 5	1/12 1/12
Example. Artillery travels 60 min.on hilly road, going up hill a total of 100 ft. (vertically) and down* hill a total of 50 ft. Required actual distance traveled: 117 X 60=7020 yds., distance if road had been level. 10/100 X 10 + 10/50 X 60=400 yds. 7020 -- 400=6620 yds. actually traveled.
