Here is what I find noted.
"SEPTEMBER 22d, the Erbprinz, with a chosen Corps of 15,000, mostly English, left these Diemel regions towards Wesel, at his speediest.
September 29th, Erbprinz and vanguard, Corps rapidly following, are got to Dorsten, within 20 miles of Wesel.

A most swift Erbprinz; likely for such work.

And it is thought by judges, Had he had either siege-artillery or scaling apparatus, he might really have attacked Wesel with good chance upon it.

But he has not even a ladder ready, much less a siege-gun.

Siege-guns are at Bielefeld [come from Bremen, I suppose, by English boating, up the Weser so far]; but that is six score miles of wheel-carriage; roads bad, and threatening to be worse, as it is equinoctial weather.
