Leuthen might be attacked with some chance of success, but Sagschuetz offered by far the most favourable opening for attack.

The formation of the ground offered special facilities for the movement being effected without the Austrians being aware of what was taking place, for there was a depression behind the swells and broken ground in front of the Austrian centre, by which the Prussians could march from Borne, unseen by the enemy, until they approached Sagschuetz.
It was three hours after Frederick had taken up his place before the four columns had all reached Borne.

As soon as they were in readiness there, they were ordered to march with all speed as far as Radaxford, thence to march in oblique order against the Austrian left.
The Austrians, all this time, could observe a group of horsemen on the hill, moving sometimes this way sometimes that, but more than this they could not see.

The conjectures were various, as hour passed after hour.

Daun believed that the Prussians must have marched away south, with the intention of falling upon the magazines in Bohemia, and that the cavalry seen moving along the hills were placed there to defend the Prussians from being taken in flank, or in rear, while thus marching.
