On the evening of July 12 the enemy assumed the offensive on the Narew front.
On the 14th we were at Roshan on the Narew, which is here a small river with fords in the neighbourhood.
To the southeast the river Pisseck forms the outlet for one of the lakes and flows toward the Narew.
The Russian Army of the Narew had, in the meantime, pushed its advance with equal rapidity and success from the south.
A right bank tributary of the Bug, the river Narew, is worth notice, because along it we find a chain of Russian forts.
The Russians also had collected large forces on the Narew, and were hurrying them toward Przasnysz on roads covering a wide front.
A tremendous attack was launched in the direction of the Narew by the army of General von Gallwitz.
The crossing of the Narew between these places was now in German hands, and strong forces were advancing on the southern shore.
