GERMANY THE AGGRESSOR X The Alemans first came into conflict with the Romans about A.D. 213, They attacked the frontier of the Empire at its weakest point, namely, the Limes Rhaeticus et Gennanicus which linked the Rhine and the Danube. The details of half a century of war are obscure, but by A.D. 260 the whole of the Agri Decumates, as well as part of Rhaetia, had passed into permanent Germanic occupation. The absorption of the Romans in the defence of Southern Gaul against the Alemans provided the occasion for formidable incursions of the Franks into 3ie Northern province. The first attack was de- livered in A.D. 253, and before many years had passed the Franks had succeeded in establishing themselves on the left bank of the Lower Rhine. They were a difficult foe to deal with, for not only were they foul fighters, but they were also infidels with whom no binding agreements could be made. Says Gibbon, *an inconstant spirit, a thirst for rapine, and a dis- regard for the most solemn treaties disgraced the character of the Franks/ Mr Sergeant makes the same remarks concerning the ancient Germans gener- ally: *A Roman general opposed to the country- men of Hermann could never hold himself safe under the terms of a truce.' * Bottomless treachery as well as merciless ferocity marked all the race, * L, Sergeant, The Franks, p. 47, 26
