What command did Petrov have during World War One? edit

This article says he led the 4th Bulgarian Army, yet the Bulgarian and Russian articles say that it was the 3rd. Anybody know for sure? — Preceding unsigned comment added by Kndimov (talkcontribs) 23:29, 20 January 2014 (UTC)Reply

I'd stick with what bg.wiki has to say in the matter. One, the article there has actual sources. Two, it was third army that operated in the area (and moved towards Pirot) and fourth army was further to the South.--Laveol T 05:54, 21 January 2014 (UTC)Reply
