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

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

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

In p. 359. he says: The king "per Suinam invectus, Julinum oppidum,
