E. A. Thompson ("Britain, A.D. 406–410", in "Britannia", 8 (1977), pp. 303–318) offered a more provocative theory to explain the expulsion of officials and appeal for Roman aid. He suggested that a revolt consisting of dissident peasants, not unlike the Bagaudae of Gaul, also existing in Britain, and when they revolted and expelled the Roman officials, the landowning class then made an appeal for Roman aid. There is no direct textual statement of this, though it might be plausible if the definition of 'bagaudae' is changed to fit the circumstances. There is no need to do so, as any number of rational scenarios already fit the circumstances. There is the possibility that some form of bagaudae existed in Britain, but were not necessarily relevant to the events of 409 and 410. The alleged ubiquity of Pelagianism amongst the British population may have contributed to such a movement if it had existed, not to mention large-scale purges amongst the British elite over previous decades. Among the works that mention but skirt the issue is Koch's "Celtic Culture" (2005), which cites Thompson's translation of Zosimus and goes on to say "The revolt in Britain may have involved bacaudae or peasant rebels as was the case in Armorica, but this is not certain."
