The number of prisoners captured by the Russians continually increased. Exclusive of those already reported--namely, 958 officers, and more than 51,000 Austrian and German soldiers, they captured in the course of the fighting on June 8, 1916, 185 officers and 13,714 men, making the totals so far registered in the present operations 1,143 officers and 64,714 men. The next day, June 9, 1916, the troops under General Brussilov continued the offensive and the pursuit of the retreating Austrians. Fighting with the latter's rear guards, they crossed the river Styr above and below Lutsk. In Galicia, northwest of Tarnopol, in the regions of Gliadki and Cebrow, heavy fighting developed for the possession of heights, which changed hands several times. During that day's fighting the Russians captured again large numbers of Austrians, consisting of ninety-seven officers and 5,500 men and eleven guns, making a total up to the present of 1,240 officers and about 71,000 men, ninety-four guns, 167 machine guns, fifty-three mortars, and a large quantity of other war material. At dawn of June 10, 1916, Russian troops entered Buczacz on the west bank of the Strypa and, developing the offensive along the Dniester, carried the village of Scianka, eight miles west of the Strypa. In the village of Potok Zloty, four miles west of the Strypa, they seized a large artillery park and large quantities of shells. In the north the Germans again attempted to relieve the pressure on their allies by attacking in force at many points. Artillery duels were fought along the Dvina front and on the Oginski Canal. Without let up, however, the Russian advance continued. So furious and swift was the onslaught of the czar's armies that the Austrians lost thousands upon thousands of prisoners and vast masses of war material of every kind. For instance, in one sector alone the Austrians were forced to retreat so rapidly that the Russians were able to gather in, according to official reports, twenty-one searchlights, two supply trains, twenty-nine field kitchens, forty-seven machine guns, 193 tons of barbed wire, 1,000 concrete girders, 7,000,000 concrete cubes, 160 tons of coal, enormous stores of ammunition, and a great quantity of arms and other war material. In another sector they captured 30,000 rounds of rifle ammunition, 300 boxes of machine-gun ammunition, 200 boxes of hand grenades, 1,000 rifles in good condition, four machine guns, two optical range finders, and even a brand-new Norton well, a portable contrivance for the supply of drinking water. The prisoners captured during June 10, 1916, comprised one general, 409 officers, and 35,100 soldiers. The material booty included thirty guns, thirteen machine guns, and five trench mortars. The total Russian captures in the course of about a week thus amount to one general, 1,649 officers, more than 106,000 soldiers, 124 guns of all sorts, 180 machine guns, and fifty-eight trench mortars.
