The catalyst for the Second Punic War lay in  Hannibal's attack on Rome's ally, Saguntum.

第二次布匿战争的催化剂在于汉尼拔对罗马盟友萨贡图的进攻。

Carthage would not give Saguntum back, but Hannibal did indeed obediently head for Rome with a little bit of company, his army.

但迦太基人不愿归还萨贡托，但汉尼拔却顺从地到达罗马但他却带着陪同，那就是他的军队。

The Romans knew that Carthage would eventually attack Saguntum and that they would have to defend Saguntum, and that a second Punic War would result.

罗马人知道迦太基最后会攻打萨贡托也相信他们会打败萨贡托，那也就是第二次布匿战争的结果。
