Major C. Fleming-Williams uses skis to stop him sinking when he walks over mud.
Item title reads - Malden. Mudlarking Made Easy. Major C. Fleming-Williams, "discoverer" of new sport of ski-running on mud.
The Major walks towards us through a river, he emerges and we see he is wearing skis, he walks across the mud on them with the help of a ski pole. He shoots his gun at something and carries on walking with some difficulty on his skis. We see another man trying to walk through the mud in his boots, he is having difficulty doing this. The Major, still wearing his skis, walks nonchalantly along behind him.
