question about a use of gestoßen

[edmont]

The context from which the German sentence below comes seems to indicate that Philipp Mittwich joined the "Bewegung" mentioned in the sentence. But I haven't found in any of several online dictionaries a use of gestoßen that might mean "joined" -- though perhaps "tumbled to" could work. Is there any way that gestoßen below could mean something like "joined"?

...with Philipp Mittwich -- er war Delegierter Württembergs auf dem ersten Rätekongreß -- war zudem ein bekannteres USPD-Mitglied zur Bewegung gestoßen.

Thank you for any assistance.

It's the Perfect of

zu jemandem/etwas (Dative) stoßen

This does indeed mean join. I'm not sure where this would be listed in a dictionary.

Thank you, tiorthan!  I see my error. I looked in dictionaries for uses of gestoßen.  I should have looked instead for uses of stoßen.  I found "join" right away.
