I want to know the answer to the following question:
Who was in charge of the Russian Caucasus Army of Imperial forces?
All the background I'm provided with is that "Although the Russian Caucasus Army of Imperial forces commanded by Nikolai Yudenich and Armenians in volunteer units and Armenian militia led by Andranik Ozanian and Tovmas Nazarbekian succeeded in gaining most of Ottoman Armenia during World War I, their gains were lost with the Bolshevik Revolution of 1917.[citation needed]". Is that enough to answer the question?
Answer: yes
