The Bulgarian army was spreated on a large area that gave a change to Turks to assoult to the north of the Bulgars.But The units of the Turkish army were also at far distances. Turks needed time to collect all forces together. The HQ of the Şark Ordusu came to Lüleburgaz from Istanbul.

Nazım Pasha who was the vice Commander in chief of the Ottoman Turkish Armies insisted to assoult to Bulgars. To assoult againts 2 Bulgar Armies with a Turkish Army was a suicide.
