Prince Maurice of Dessau had been ordered to move with the right wing of Keith's army, 15,000 strong, to take up a position in the Austrian rear.

This position he should have reached hours before, but in his passage down a narrow lane, some of the pontoons for bridging the river were injured.

When the bridge was put together, it proved too short to reach the opposite bank.
The cavalry in vain endeavoured to swim the river.

The stream was too strong, and Frederick's masterly combination broke down; and the bulk of the Austrians, instead of being forced to surrender, were simply shut up in Prague with its garrison.
The battle of Prague was one of the fiercest ever fought.

The Austrian army had improved wonderfully, since the Silesian war.
Their artillery were specially good, their infantry had adopted many of the Prussian improvements and, had Browne been in sole command, and had he escaped unwounded, the issue of the day might have been changed.
