However, in 405, Stilicho was distracted by a fresh invasion of Northern Italy. Another group of Goths fleeing the Huns, led by one Radagaisus, devastated the north of Italy for six months before Stilicho could muster enough forces to take the field against them. Stilicho recalled troops from Roman Britain, and the depth of the crisis was shown when he urged all Roman soldiers to allow their personal slaves to fight beside them. His forces, including Hun and Alan auxiliaries, may in the end have totalled rather less than 15,000 men. Radagaisus was defeated and executed, while 12,000 prisoners from the defeated horde were drafted into Stilicho's service. Stilicho continued negotiations with Alaric; Flavius Aetius, son of one of Stilicho's major supporters, was sent as a hostage to Alaric in 405. In 406, Stilicho heard of new invaders and rebels who had appeared in the northern provinces. He insisted on making peace with Alaric, probably on the basis that Alaric would prepare to move either against the Eastern court or against the rebels in Gaul. The Senate deeply resented peace with Alaric. In 407, Alaric marched into Noricum and demanded a large payment for his expensive efforts in Stilicho's interests. The senate, "inspired by the courage, rather than the wisdom, of their predecessors," preferred war. One senator famously declaimed "Non est ista pax, sed pactio servitutis" ("This is not peace, but a pact of servitude"). Stilicho paid Alaric four thousand pounds of gold nevertheless. Stilicho sent Sarus, a Gothic general, over the Alps to face the usurper Constantine III. Sarus lost this campaign and barely escaped, having to leave his baggage to the bandits who now infested the Alpine passes.
