Russian Steam Bath
Pioneers erected a Russian steam bath in the transport lines - I imagine this was some sort of sauna. Presumably quite a novelty in 1918 for men from England
Josie, Erik posted a question re this a year ago. See link for my Steam Baths comment, also other comments on this link:
i.e A Russian vapour bath is being fitted up into the Rest Station. I believe they are steam baths.
In another article there is mention of Steam sterilizers:
Steam sterilizers were horse drawn, of small capacity, and of minimal utility. A device called the “Russian Pit” hot air delouser came along late in the war and had a capacity much greater than available steam sterilizers. The British also developed a combination of naphthalene, creosote, and iodoform made into a paste which could be applied to the seams of uniforms with a good result of eliminating lice in just a few hours.
Also Article re Communal baths (Re Typical life of soldiers).
Time spent out of the line at least offered the opportunity for the front line soldier to get clean. Communal baths would be set up and lice-infested clothing steam-cleaned.
