Early evidence of the lack of realistic thinking in Bulgarian leadership was that although Russia had sent clear warnings expressed for the first time on 5 November 1912 (well before the First Battle of Çatalca) that if the Bulgarian Army occupied Constantinople they would attack it, they continued their attempts to take the city.
Varajane tõend realistliku mõtlemise puudumisest Bulgaaria juhtkonnas oli, et kuigi Venemaa oli saatnud 5. novembril 1912 esimest korda selge hoiatuse (enne Esimest Çatalca lahingut), et kui Bulgaaria armee okupeerib Konstantinoopoli, siis teda rünnatakse, jätkas Bulgaaria oma katseid linn ära võtta.
