The terror at Vienna, nevertheless, is very great: "A day of terror," says one who was there; "I will not trust myself to describe the sensation which this news, 'Friedrich in Bohemia again!' produced among all ranks of people." [Cogniazzo, iv.

316, 320, 321; Preuss, iv.

196-200.] Schmettau says, "Friedrich, cheated of his Mahren schemes, was still in time; the Austrian position being indeed strong, but not being even yet quite ready." Friedrich himself, however, on reconnoitring, thought differently.
