Yep, Bremen and its small neighbourtown Verden, Wismar, and all of western Pomerania became Swedish in the peace treaty of Westphalia 1648 after the 30th Year War. In those days, no-one thought of Swedes as cowards, but as the horror of Europe.

Do you know that the Swedish army as one of very few actually captured Moscow in 1611? It had little political importance, though, since they had do withdraw after a short while.
