My War Memories, 1914-1918 communication of the gth Army remained under our control. It was necessary for our further advance that I should make very many arrangements direct with this Army. The movements of the gth and I2th Armies were very closely related. General Headquarters were far too busy for me to venture to trouble them with such details. The capture of Warsaw gave us special satisfaction. We had fought so hard for it in the autumn of 1914. In that campaign were laid the foundations of the present successes, of which the occupation of Warsaw was the sign and symbol. During the following days Field-Marshal Prince Leopold of Bavaria's Army Group crossed the Vistula between Ivangorod and Warsaw on a wide front. Once again General Headquarters attempted to effect an enveloping movement by directing this Army Group straight on Brest-Litovsk, whilst strong Russian forces were still north of Lublin. But in vain ; the Russians got away. Whilst Field-Marshal von Mackensen was struggling towards Brest-Litovsk, Prince Leopold's group had advanced to the Bug below the fortress. After the crossing of the Narew by the I2th Army at the end of July, General von Gallwitz had cast his eyes due south towards the Bug. He still hoped to succeed in enveloping the enemy who had not yet retreated from Warsaw. With that end in view he made his principal thrust with his right wing, from Wyshkow to the Bug. As I had feared and General von Gallwitz had also thought possible, these hopes were not fulfilled. Somewhere about the loth, the I2th Army received instructions to march east, with the right wing moving up the Bug. In this way it came into close touch with the 8th Army, which, after the fall of Ostrolenka on August 5th, had gained more ground on the southern bank of the Narew, and was now advancing with Lomza as its objective. In the meantime Sieroc and Segershe had fallen, also Dombe ; Novo Georgievsk had been invested on all sides. The capture of this fortress was entrusted by the Field-Marshal to General Von Beseler. The troops of the gth and I2th Armies investing Novo Georgievsk were placed under his command* He also 154
