Panzer Campaigns teaser guessing thread

[ComradeP]

Maybe my eyes are bad, but it seems as if the "Donaukanal" (Danube Canal) is missing? Once the major distributiary of the Danube, it is still a major obstacle in the center of the city. Not having it would be a major oversight.  

In terms of PzCampaigns, it should be represented as a river. The bridges leading over it (Salztorbrücke, Schwedenbrücke, Marienbrücke, Aspernbrücke, ...) have been demolished in April and Soviets required pioneers to cross it.

Good point, in the 1:500.000 map used by Strela most of the canal isn't visible. It's hard to tell if it's currently represented as a stream, but it doesn't look like it.
