But was Julin drowned at all?  Helmold does not say that it was (his account is in Book i. c. 2. s. 5.); and he does say that it was not, but destroyed by a certain Danish king.  It is most inconceivable that he should not have known who the Danish king was, if it happened in his own time.  The passage savours of much later interpolation.

Koch, Rivol. vol. i. p. 280., states positively that Julin was Wollin, and was destroyed by Waldemar I. in 1175, for which he seems to rely upon Helmold, or at least his continuator, Arnold.  Helmold himself died in 1170.

Saxo Grammaticus lived at that time, and was probably well acquainted with the events, since he was intimate with Archbishop Absolon, who took part in them in a military as well as ecclesiastical sense.  In p. 333. he says: 

“Waldemar the 1st, goes with a fleet through the month of the river Zwina, then to the river which adjoins Julin and Camin, and has its mouth divided into two.  There was a long bridge joining the walls of Julin.  The king having landed ’ex adverso urbis in ripa Australi, pontem disjici jussit.’  The king cleared the way for his fleet; got to an island Chrisztoa; crossed the river and went to Camin.  He went out to sea by that mouth.”

This is given very much at length.

All this is the geography of the present day, and the names, if you read Wollin for Julin.  The Oder expands into a wide lake, shut off from the sea by a bar of land, through which there are three channels.  The Zwein is the middle one of the three; that which passes by Wollin and Kimmin is the eastern one.

In p. 347. he says: 

“Rex ... classem ...  Zuinsibus ostiis inserit, Julinique vacuas defensoribus aedes, incendio adortus, rehabitatae urbis novitatem, iterata penatium strage, consumpsit....  Juilinenses, cum urbis uae recenses ruinas, ferendae obsidioni, inhabiles cernerent, perinde ac viribus orbati, deserta patria, praesidium Caminense petiverunt, aliena amplexi moenia, qui propria tueri diffiderent.”

In p. 359. he says:  The king “per Suinam invectus, Julinum oppidum, incolarum fuga desertam, incendio tentat.”

Saxo mentions Julin, p. 182-24.:  “Nobilissimum illius provinciae oppidum,” under Harold Blatand, King of Denmark, who reigned in the latter half of the ninth century.  He put a body of troops into it, who became dreadful pirates.

In p. 225. he says that the Danes compelled them to give up their pirates, who were punished.  In p. 381., in the reign of Canute, son of Waldemar, there is an expedition against the Julinenses, the result of which is expressed “Julinensium rebus absumptis.”

In p. 382., the king sets out for Julin, but seems to have attacked only Camin.  Waldemar died in 1182, Canute, 1202 (Koch.)

Arnold (b. iii. c. 8. s. 4.) speaks of the Sclavi as finally subdued and made tributary, about 1185.
