I know its short-lived nature makes it difficult to analyze in depth politically, but I have recently heard claims that while it made reforms regarding factory conditions, it and its army made notable efforts to return lands to landlords from the peasants who had taken it over post-revolution(s). This seems strange, as I had understood the major pre-revolution(s) distinction between SRs and both Bolsheviks and Mensheviks was the SR's focus on the peasantry and land redistribution, compared to the proletariat-focus of the latter pair. Is this all Soviet-era propaganda, or is there genuine truth to the claims of the KOMUCH just being an SR velvet-glove to a reactionary iron fist?
I would also appreciate recommendations of any good English-language literature on the Komuch.
It's been too long time since I've read about the topic to answer your question, but a good source is Jonathon Smele's Civil War in Siberia, which is a very extensive study of Kolchak's regime but also of the wider war in the east, and includes a lot of information on KOMUCH and other Siberian White forces. He also has a smaller and more accessible recent work called The 'Russian' Civil Wars but I imagine it has less to say about KOMUCH since it is not specifically about Siberia.
