the first attack on the celtic tribes of what is now wales was made under the legatus publius ostorius scapula about 48 ad. ostorius first attacked the deceangli in the north-east, who appear to have surrendered with little resistance. he then spent several years campaigning against the silures and the ordovices. their resistance was led by caratacus, who had fled what is now southeast england when it was conquered by the romans. he first led the silures, then moved to the territory of the ordovices, where he was defeated by ostorius in 51 ad. caratacus fled to the brigantes, whose queen handed him over to the romans.
