I want to know the answer to the following question:
Who led the Soviet Eleventh Army?
All the background I'm provided with is that "Turkish forces under the command of Kazım Karabekir captured Armenian territories that Russia had annexed in the aftermath of the 1877–1878 Russo-Turkish War and occupied the old city of Alexandropol (present-day Gyumri).". Is that enough to answer the question?
Answer: no
