To Germany!

The latter is not very profitable: the cities are poor and distances great, meaning you need to cover a long border with garrisons for little financial reward.

Silengolandam should make for good revenue though, as it has two silver mines and two trade-boosting uniques. Together with paved roads that'll provide a very solid income, much like Helvetis.

The Sweboz regionals available to the Celts are nothing to write home about, and IIRC you can get better German units as mercs.

You should be able to train Dugundiz and Celto-Germanic spearmen. Both are very decent line spearmen that should nicely complement the Gallic armies (unless of course you don't care about historicity and just start fielding mass Bataroas/Mori Gaesum for the lulz). Also, there are Worgozez and mercenary nobles around.

If your objective is merely to neutralize the Sweboz, why don't you simply garrison the river-crossings?They will waste their armies on your defensive line and you are free to take on more dangerous (and richer) foes.

I support that notion. Just block them like the historical Gauls tried to do, and pillage Iberia and Italia instead. Possibly even North Africa...
