4. Upon the basis of this decision the movement of the troops to the frontier was arranged. The railway system, as has been seen, did not admit of moving the corps directly and speedily to Görlitz and Schweidnitz. Five railways in all were available, leading to points on the Prussian frontier facing the kingdom of Saxony and the Austrian Empire. They ended at Zeitz, Halle, Hertzberg, Görlitz, and Schweidnitz (or Neisse), places scattered along a curve some 250 miles long. The quickest practicable way of assembling the army was to use all these railways at once, and when the troops had thus been deposited on the frontier to continue the concentration by marches. The shortest lines of march to assemble the whole army would be the radii leading to the centre of the curve; but this was in the enemy's territory, so that these lines, if they had been for other reasons desirable, could not be adopted before war had been declared. The alternative was to concentrate by marches along the circumference, and this was the plan adopted. Each corps, as soon as its debarkation from the train was complete, was marched along the arc towards the point of concentration selected for it. The corps from Posen and Silesia, collected at Schweidnitz and Neisse (grouped together as the second army under the Crown Prince), were moved to their right to Landshut and Waldenburg.[8] Those of Westphalia (half a corps) and Rhenish Prussia were detrained at Zeitz and Halle, and marched round the frontier of Saxony to the point where the Elbe emerges from that kingdom. These troops, with the reserve corps from Berlin, formed the Elbe army, destined to continue its eastward movement by the invasion of Saxony. The corps from Pomerania, Brandenburg, and Prussian Saxony, were combined into the first army, under Prince Frederick Charles. They were first assembled between Torgau and Cottbus, and then marched along the frontier towards Görlitz, reaching the western corner of Silesia (neighbourhood of Hoyerswerda) about the end of the first week in June, when the other movements described were also completed. 5. The staff was now anxious to begin the campaign. The three armies could not be united on Prussian soil without leaving some important district unprotected, nor await where they were the Austrian attack without the risk that one of them in isolation might be exposed to the blows of a superior force. This same risk only would be incurred in the attempt to meet by a concentric advance towards some point of Austrian territory; it would increase with every additional day allowed for the Austrian preparations. But the king still thought a settlement possible, and would not permit hostilities to commence.
