General von Mackensen continued toward Lemberg, the capital of Galicia. On June 18th, when the victorious German armies were approaching the gates of Lemberg, the Russian losses were estimated at 400,000 dead and wounded, and 300,000 prisoners, besides 100,000 lost before Marshal von Hindenburg's forces in Poland and Courland. On June 23d Lemberg fell. The weakness of Russia in this campaign arose from the exhaustion of her ammunition supplies, but great shipments of such supplies were being constantly forwarded from Vladivostock. When the German army crossed the San, Wilhelm II, then German Emperor, was present. It is interesting to look back on the scene. Here is a paragraph from the account of the Wolff Telegraphic Bureau: "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 Jaroslav 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." While the great offensive in Galicia was well under way, the Germans were pushing forward in East Prussia. Finding little resistance they ultimately invaded Courland, captured Libau, and established themselves firmly in that province. The sweep of the victorious German armies through Galicia was continued into Poland. On July 19th William the War Lord bombastically telegraphed his sister, the Queen of Greece, to the effect that he had "paralyzed Russia for at least six months to come" and was on the eve of "delivering a coup on the western front that will make all Europe tremble." It would be futile to recount the details of the various German victories which followed the advance into Poland. On July 24th, the German line ran from Novgorod in the north, south of Przasnysz, thence to Novogeorgievsk, then swinging to the southeast below Warsaw it passed close to the west of Ivangorad, Lublin, Chelm, and then south to a point just east of Lemberg. Warsaw at that time was in the jaws of the German nutcracker. On July 21st, the bells in all the churches throughout Russia clanged a call to prayer for twenty-four hours' continual service of intercession for victory. In spite of the heat the churches were packed. Hour after hour the people stood wedged together, while the priests and choirs chanted their litanies. Outside the Kamian Cathedral an open-air mass was celebrated in the presence of an enormous crowd. But the German victories continued.
