"The Bulgarians continued their advance into Eastern Macedonia unopposed by the Greek garrison, and it was estimated that by the end of August the enemy's forces, extending from Demir Hissar southward in the Seres sector of the Struma front, comprised the complete Seventh Bulgarian Division, with two or three regiments of the Eleventh Macedonian Division, which had moved eastward from their positions on the Beles Mountain to act as a reserve to the Seventh Division, and at the same time to occupy the defenses from Vetrina-Pujovo northward. Opposite the Lower Struma was a brigade of the Second Division, with a brigade of the Tenth Division, in occupation of the coast and the zone of country between Orfano and the Drama-Kavala road. This brigade of the Tenth Division was supported by another brigade in the Drama Kavala area. As a result of this advance and of a similar move in the west General Sarrail decided to intrust to the British Army the task of maintaining the greater portion of the right and center of the allied line. [Sidenote: Northumberland Fusiliers capture Nevolien.] "On September 10, 1916, detachments crossed the river above Lake Tachinos at five places between Bajraktar Mah and Dragos, while a sixth detachment crossed lower down at Neohori. The villages of Oraoman and Kato Gudeli were occupied, and Northumberland Fusiliers gallantly captured Nevolien, taking thirty prisoners and driving the enemy out of the village. The latter lost heavily during their retirement and in their subsequent counterattack. They also suffered severely from our artillery fire in attempting to follow our prearranged movements to regain the right bank of the river. [Sidenote: Rise in the Struma River hinders operations.] "On the 15th similar operations were undertaken, six small columns crossing the river between Lake Tachinos and Orljak bridge. The villages of Kato Gudeli, Dzami Mah, Agomah, and Komarjan were burned and twenty-seven prisoners were taken. The enemy's counterattacks completely broke down under the accurate fire of our guns on the right bank of the river. On the 23d a similar scheme was put into action, but a sudden rise of three feet in the Struma interfered with the bridging operations. Nevertheless, the enemy's trenches at Yenimah were captured, fourteen prisoners taken, and three other villages raided. Considerable help was given on each occasion by the French detachment under Colonel Bescoins, and much information was obtained which proved to be of considerable value during subsequent operations.
