Suddenly, on the morning of October 2, 1916, the Rumanians threw a pontoon bridge across the Danube at Rahova, about halfway between Rustchuk and Tutrakan, and well in the rear of Mackensen's line. Before the small Bulgarian forces stationed at this point were aware of what had happened they were completely overwhelmed by the Rumanians, who were streaming across the bridge. All the villages in the neighborhood were seized and for twenty-four hours it was expected that Mackensen was about to suffer a sensational repulse. But apparently the Rumanians lacked the forces necessary for the successful carrying out of what would have been a brilliant stroke, or possibly the Bulgarian forces which appeared here against them were larger than had been expected, for the next day they announced that the force which had been thrown across the river had again retired, unharmed, the object of its demonstration having been accomplished. According to the Bulgarian accounts their retreat was forced because of the appearance of an Austrian monitor, which began shelling and destroying the pontoon bridge, and that before the retreat had been completed the bridge had been destroyed and a large remnant of the Rumanian force had been captured or killed. In general, however, the fighting during these first few days of the month gave neither side any advantage, and again the situation calmed down to comparative inactivity. That the retirement of the Rumanians was well ordered is shown by the fact that even the Berlin dispatches claimed very few prisoners, in addition to a thousand taken at Brasso, while the Austro-Germans had lost considerably over a thousand. On the 6th Fogaras had been relinquished. North and east of Brasso the Rumanians had also retreated. On the 8th Berlin announced that "the entire eastern front of the enemy was in retreat." This was, in general, quite true, except that for a few days longer they still held their positions in the valley of the Maros. Aside from the advantage in his superiority of numbers, Falkenhayn also had at his disposal the better railroad accommodations. A line running parallel with almost the entire front enabled him to shift his forces back and forth, wherever the contingencies of the situation made them needed most. By the 12th he was facing the Rumanians in the passes. Heavy fighting then began developing at Torzburg, Predeal, and Buzau Passes. Finally the Rumanians were forced back toward Crasna on the frontier. A critical moment seemed imminent. Averescu, who had defeated Mackensen, was now recalled from the Dobrudja and sent to take command of the Rumanian forces defending the passes behind Brasso. By the middle of the second week of October, 1916, the Rumanians had lost all the territory they had taken, except a little in the northeast. The German-Austrian pressure was now heaviest in two areas: about the passes behind Brasso and before the Gyimes Pass in the northeast.
