History of Friedrich II of Prussia, Volume 19 by Thomas Carlyle

Sunday, July 29th, at Frankfurt-on-Oder divine worship was broken in upon, and the poor City thrown into consternation, by actual advent, or as good as advent, of the Russians: "On the Crossen road, close by; coming, come! " And they did undeniably appear, next morning, in force; on the opposite, eastern or Kunersdorf side of the River, on the top of the Oder-Dam there; and demanded instant admission, under penalty of general death by fire.

Within the Town stood Major Arnim, a Veteran of those parts, with 400 militia; these, with their muskets and with two cannon, are the only defence of Frankfurt, The Town has Gates; but its walls, I doubt, are mainly garden-walls and house-walls. On the eastern side, the River, especially if you have cannon on the Bridge, gives it something of protection; but on the western and all other sides, it is overhung by heights. This Frankfurt, like its bigger Namesake on the Mayn, is known as a busy trading place, its Fairs much frequented in those Eastern parts; and is believed by the Russians to be far richer than it is. The reader, as there happens to be ocular testimony extant, [Johann Zudwig Kriele, SCHLACHT BEI KUNERSDORF, MIT &C. (Berlin, 1801). Kriele was subsequent Pastor in the Parish, an excellent intelligent man: has compiled in brief form, with an elaborate Chart too, a clear account of everything, in the Battle and before and after it.] may like to see a little how they behaved there.
