Problems experienced by armoured fighting vehicles (‘tanks’) crossing soft ground became apparent during World War I. These were avoided early in World War II by the use of ‘going’ maps in North Africa from 1940 to 1943, but when operations moved to NW Europe it was realized that there would be the additional problem of changes in ground conditions due to variations in soil moisture according to the weather. This led to an investigation into factors controlling the movement of tracked vehicles over water-softened ground, beginning in July 1944 with the establishment of the ‘Mud Committee’, tasked to consider problems in light of recent developments in the (then) new science of soil mechanics. Contemporary ideas, as applied to building and road construction, were found to be inapplicable, and attention was therefore focused on empirical trials. The Committee faced the constant problem of balancing the requirement for short-term results with the need for long-term research. As a result, it failed to meet many of its objectives by the end of hostilities, but its work did provide a sound basis for the development of a method of classifying soils for military purposes and for future work on track design.
