The Romans fought a war in Africa against the Numidians led by their King, Jugurtha (112-104 BCE). The Romans won. Sallust tells the tale of the war, but he ends it with the ominous anticipation of future dangers:
Sallust, Bellum Jugurthinum 114
“At that time, a battle was fought and lost against the Gauls by the generals Quintus Caepio and Gnaeus Mallius. Because of this, all of Italy quaked in fear. The Romans from that time down to our own have believed that while all other matters give way to our virtue, with the Gauls it is an issue of safety, not glory.
After it was made known that the war in Numidia was concluded and that Jugurtha was being returned as a prisoner, Marius was made consul even though absent, and Gaul was set as his province. On the first day of January, he celebrated his triumph as consul in great glory. And at that moment, the hope and health of the state resided with him.”
Per idem tempus adversum Gallos ab ducibus nostris Q. Caepione et Cn. Manlio male pugnatum. Quo metu Italia omnis contremuerat. Illincque [et inde] usque ad nostram memoriam Romani sic habuere, alia omnia virtuti suae prona esse, cum Gallis pro salute, non pro gloria certare. Sed postquam bellum in Numidia confectum et Iugurtham Romam vinctum adduci nuntiatum est, Marius consul absens factus est, et ei decreta provincia Gallia, isque Kalendis Ianuariis magna gloria consul triumphavit. Et ea tempestate spes atque opes civitatis in illo sitae.
