On the 27th, our positions were as follows. The right wing occupied the greater part of Mount Cesma, and, together with the French troops, drove back the enemy from the Harilovo-Diviak area. The main column of the centre, having advanced beyond Pustareka, had reached Karaul Kruska, and the flanking column on the left, which, after having passed through Kochista, reached the neighbourhood of Tzer; the left, after occupying Priblitzi, pushed forward through Dolentzi to Sop, along the Monastir-Kichevo road. On the 28th, the right column completed the occupation of Mount Cesma, and advanced towards the Stramol and Baba mountains, north-east of Sop; the principal column and the centre, after overcoming the enemy’s vigorous resistance, occupied a line of heights 3 km. to the east of that village, while its left flanking column co-operated in the action from Tzer. The left reached Hill 932 to the south of Sop, in support of the action of the centre. The Bulgarians here were in very strong positions. With numerous forces of infantry, a great many machine guns, and several field and heavy batteries withdrawn from the Monastir front, they had entrenched themselves on formidable lines in the Sop gorge, where they were prepared to offer a desperate resistance. The following day the Sicilia Brigade succeeded in driving the enemy from Mounts Stramol and Baba, and after occupying these positions pushed on towards Plasnitza to co-operate with the 11th Colonial Division, which was attacking the enemy entrenched on the heights of Izitza to the north of the Yelika valley. In the centre our battalions renewed the attack on Sop from the south-east and east so as to pin down the enemy, while those of the right column executed a turning movement from Karaul Kruska towards the north-east to cut off their retreat. The fighting during those days was very fierce, and cost us 500 casualties. The Bulgars had been strengthened on the night of the 28th-29th by two more regiments and several machine-gun companies, which had fallen back from Monastir, but had been recalled. The behaviour of our troops in all these very stiff engagements against an enemy superior in numbers, in dominating positions, and supplied with great abundance of artillery of all calibres and machine-guns, had been admirable, and it must be remembered that they were exhausted by the long and tiring marches over very rough country. If the Serbs had advanced further, they had, however, after the first two days found an enemy that resisted far less vigorously than was the case in our sector. Furthermore, the enemy opposed to us was directly under German Command--Army Command, Corps Command, and partly Divisional Command--and was stiffened by the presence of several German detachments.
