These battles and successes took place on the 17th of May in the presence of the German Emperor, who, on the same day, conferred upon the Chief of Staff of the army here engaged, Colonel von Seeckt, the order _pour le mérite_, the commander of the army, General von Mackensen, having already received special honors. The Emperor had hurried forward to his troops by automobile. On the way he was greeted with loud hurrahs by the wounded riding back in wagons. On the heights of Jaroslau the Emperor met Prince Eitel Friedrich, and then, from several points of observation, for hours followed with keen attention the progress of the battle for the crossing. In the days from the 18th to the 20th of May the Teutonic allies pressed on further toward the east, northeast, and north, threw the enemy out of Sieniawa and took up positions on the east bank of the river upon a front of twenty or thirty kilometers. The enemy withdrew behind the Lerbaczowa stream. All his attempts to win back the lost ground were unsuccessful, although in the days from the 13th to the 20th of May he brought on no less than six fresh divisions to stem our advance at and beyond Jaroslau. Altogether, the Russian command had since the beginning of the operation thrown seven army corps from other areas of the war against the front of the army of von Mackensen and against the centre and right wing of the army of Archduke Joseph Ferdinand. These were the Third Caucasian, the Fifteenth, and a combined army corps, six individual infantry regiments, the Thirty-fourth, Forty-fifth, Fifty-eighth, Sixty-second, Sixty-third, Seventy-seventh, and Eighty-first Infantry, and the Thirteenth Siberian division, not counting a cavalry division, which entered the field already in the earliest days. With the combined army corps there appeared a Caucasian infantry division, the Third, made up of Armenians and Grusinians, which till January had fought in Persia, was transferred in April to Kars, and later to Odessa, where it formed part of the so-called Army of the Bosporus. Before our front now also appeared Cossacks on foot, a special militia formation, which hitherto had fought in the Caucasus. Finally, there came on the outermost left wing of the Russians the Trans-Amoor border guards, a troop designed purely for protection of the railway in North Manchuria, whose use in this part of the area of war was probably not foreseen even in Russia. Yet the Russians still held along the lower San the bridge-head of Radymo on the west bank. The problem of the next ensuing battles was to drive him also from this point. APPROACHING PRZEMYSL.
