from "Report of the International Commission to Inquire into the Causes
and Conduct of the Balkan Wars" 1914.
Serbian-Bulgarian treaty of 13 March 1912 made provision for the partition
of Macedonia along the following lines: 'all the territory north of the
Sar range' was to go to Serbia; 'all the region east of the Rhodope range
and the Struma valley' was to go to Bulgaria. Bulgaria hoped the intervening
country should form an 'autonomous Macedonia', but, if this should prove
impossible, a new line was to be drawn leaving Kumanovo, Skoplje and Debar
to Serbia, and giving Kratovo, Veles, Bitolj (Monastir) and Ohrid to Bulgaria.
Serbia undertook to make no claim south of the line; Bulgaria reserved
the right to claim territory to the north, in which case Russia was to
act as arbitrator. The area of overlapping claims was known as the 'Contested
Zone'. "...quote from: Great Britain. Naval Intelligence Division, Geographical
