Imbecile Commandant, treacherous Garrison (Austrian deserters mainly), with stealthy Jesuits acting on them: no use asking what.

Here is the sad Narrative, in succinct form.
CAPTURE OF GLATZ (26th July, 1760).
"Loudon is a swift man, when he can get bridle; but the curb-hand of Daun is often heavy on him.

Loudon has had Glatz blockaded since June 7th; since June 23d he has had Fouquet rooted away, and the ground clear for a Siege of Glatz.

But had to abstain altogether, in the mean time; to take camp at Landshut, to march and manoeuvre about, in support of Daun, and that heavy-footed gallop of Daun's which then followed: on the whole, it was not till Friedrich went for Dresden that the Siege-Artillery, from Olmutz, could be ordered forward upon Glatz; not for a fortnight more that the Artillery could come; and, in spite of Loudon's utmost despatch, not till break of day, July 26th, that the batteries could open.

After which, such was Loudon's speed and fortune,--and so diligent had the Jesuits been in those seven weeks,--the 'Siege,' as they call it, was over in less than seven hours.
"One Colonel D'O [Piedmontese by nation, an incompetent person, known to loud Trenck during his detention here] was Commandant of Glatz, and had the principal Fortress,--for there are two, one on each side the Neisse River;--his Second was a Colonel Quadt, by birth Prussian, seemingly not very competent he either, who had command of the Old Fortress, round which lies the Town of Glatz: a little Town, abounding in Jesuits;--to whose Virgin, if readers remember, Friedrich once gave a new gown; with small effect on her, as would appear.
