That Russia was now making strong efforts to relieve the pressure on the Rumanians before Bucharest became obvious on December 1, 1916, when it was reported from Petrograd that a Russian offensive had been begun on the Bukowina border and was spreading down along the Rumanian frontier south of Kirlibaba, along a front over two hundred miles in length. Here, according to the report, the Rumanians, in cooperation with the Russians, captured a whole range of heights in the Buzeu Valley southeast of Kronstadt, while the Russians themselves reported similar progress. At the same time Berlin, while also touching on the severity of the fighting in the north, reported that the Russians were hurling themselves against Mackensen's entire front in Dobrudja. The German reports admitted that here and there the Russian attacks effected slight local gains at tremendous cost. Whatever the actual facts, this offensive movement came too late to have any material results; Bucharest, at any rate, was doomed. CHAPTER XXXI THE BATTLE OF THE RIVER ARGECHU On December 3, 1916, what appears to have been a desperate battle from the German reports took place along the river Argechu in the region before Bucharest. This is a mountain stream which, from Piteshti to southwest of Titu, is sometimes a hundred yards in width and at some points twenty meters deep, though fords are found at frequent intervals. At this time, however, the river was well flooded and only the bridges were available for crossing. At this point strong detachments of Bulgarians, Austrians, and Germans coming together from the north, east, and south met with resistance from the Rumanians on the other side of the river. For an entire day the Rumanians held back the enemy, then suddenly broke and fled so abruptly that they had not time to destroy the bridges, over which the invaders streamed after the retreating Rumanians, capturing several thousands of prisoners. On the following day the left wing of the Austro-Germans captured Tergovistea. At Piteshti the First Army of the Rumanians made another brief stand, but was driven back beyond the Titu junction of railroads from Bucharest to Campulung. South of Bucharest Russian and Rumanian forces also offered a stout resistance, but were finally compelled to retire when the enemy's cavalry cut around in their rear and threatened their line of retreat. During this one day the Germans claimed to have taken 8,000 prisoners, the Danube army capturing also thirty-five cannon and thirteen locomotives and a great amount of rolling stock.
