Stralsund, with its outer lines and inner, with its marshes, ditches, ramparts and abundant cannon to them, and leaning, one side of it, on the deep sea, which Swedish ships command as yet, is very strong. Wallenstein, we know, once tried it with furious assault, with bombardment, sap and storm; swore he would have it, "though it hung by a chain from Heaven;" but could not get it, after all his volcanic raging; and was driven away, partly by the Swedes and armed Townsfolk, chiefly by the marsh-fevers and continuous rains. Stralsund has been taken, since that, by Prussian sieging; as old men, from the Great Elector's time, still remember. [l0th-15th October, 1678 (Pauli, v. 203, 205).] To Louis Fourteenth's menacing Ambassador, Friedrich Wilhelm seems to intimate that indeed big bullying words will not take it, but that Prussian guns and men, on a just ground, still may. The details of this Siege of Stralsund are all on record, and had once a certain fame in the world; but, except as a distant echo, must not concern us here. It lasted till midwinter, under continual fierce counter-movements and desperate sallies from the Swedish Lion, standing at bay there against all the world. But Friedrich Wilhelm was vigilance itself; and he had his Anhalt-Dessaus with him, his Borcks, Buddenbrocks, Finkensteins, veteran men and captains, who had learned their art under Marlborough and Eugene. The Lion King's fierce sallies, and desperate valor, could not avail. Point after point was lost for him. Koppen, a Prussian Lieutenant-Colonel, native to the place, who has bathed in those waters in his youth, remembers that, by wading to the chin, you could get round the extremity of Charles's main outer line. Koppen states his project, gets it approved of;--wades accordingly, with a select party, under cloud of night (4th of November, eve of Gunpowder-day, a most cold-hot job); other ranked Prussian battalions awaiting intently outside, with shouldered firelock, invisible in the dark; what will become of him. Koppen wades successfully; seizes the first battery of said line,--masters said line with its batteries, the outside battalions and he. Irrepressibly, with horrible uproar from without and from within; the flying Swedes scarcely getting up the Town drawbridge, as he chased them. That important line is lost to Charles.
