Corps assembled at Monastir.3 The forcing of the Babuna Pass above Prilep .was a long and difficult business, which fell on the central column alone, as Danube I.
Corps occupied the plain from opposite Novak to Kikuricani, with its centre of gravity on the Prilep road.'
The necessity of maintaining at all costs the single supply route of the army - that through Prilep to points on the Uskub-Salonika railway - no doubt imposed a plan of battle that was to all intents and purposes frontal, for the projected movements of cavalry on Resna and over the Cerna could hardly be regarded as serious attempt at envelopment.
The region inhabited by a more or less homogeneous Albanian population may be roughly marked out by a line drawn from the Montenegrin frontier at Berane to Mitrovitza and the Servian frontier near Vranya; thence to Uskizb, Prilep, Monastir, Florina, Kastoria, Iannina and Parga.
