Origins of Caesar\'s 10th legion

[Paullus Scipio]

Probably the first Legion raised from 'non Italians' ( all Italians were Roman citizens from 90 BC IIRC ) were Caesar's 'Alaudae' believed to be raised from Gauls ( the Trans-Alpine kind ),and paid for initially by Caesar personally, (Seutonius; Julius Caesar 24) and who acquired their offical number ( Legio V ) and their citizenship sometime after their formation, when they were recognised by the Senate.... they were recruited fairly late in the Gallic Wars, and their first major action was the siege of Vercingetorix in Alesia.......
