Lest anyone should suspect me of twisting the story, I give it in the words of Sidonius's editor, writing twenty years ago.
Julius Nepos was alive to the danger that Euric might cross the Rhone; but weak as his resources were he could only hope to secure peace by negotiation.

The quaestor Licinianus had been sent into Gaul to investigate the condition of affairs on the spot....

He had now returned and it was soon only too clear that hopes based on his intervention were not likely to be fulfilled.

We find Sidonius writing for information....
He began to fear that something was going on behind his back, and that the real danger to Auvergne came no longer from determined enemies but from pusillanimous friends.

His suspicions were only too well founded.
