We have said nothing of affairs in <a class="linkToPlace" target="_blank" href="/place?placename=Spain&groupId=983&placeId=1735">Spain</a> during these years. Hasdrubal had by his wise and practical administration made great general progress, and by the foundation of the city called by some <a class="linkToPlace" target="_blank" href="/place?placename=Carthage&groupId=441&placeId=820">Carthage</a>, and by others the New Town, made a material contribution to the resources of <a class="linkToPlace" target="_blank" href="/place?placename=Carthage&groupId=441&placeId=820">Carthage</a>,
especially owing to its favourable position for action in <a class="linkToPlace" target="_blank" href="/place?placename=Spain&groupId=983&placeId=1735">Spain</a> or <a class="linkToPlace" target="_blank" href="/place?placename=Libya&groupId=686&placeId=427">Libya</a>. On a more suitable occasion we will describe its position and point out the services it can render to both these countries.
The Romans, seeing that Hasdrubal was in a fair way to create a larger and more formidable empire than <a class="linkToPlace" target="_blank" href="/place?placename=Carthage&groupId=441&placeId=820">Carthage</a> formerly possessed, resolved to begin to occupy themselves with Spanish affairs.
Finding that they had hitherto been asleep and had allowed <a class="linkToPlace" target="_blank" href="/place?placename=Carthage&groupId=441&placeId=820">Carthage</a> to build up a powerful dominion, they tried, as far as possible, to make up for lost time.
For the present they did not venture to impose orders on <a class="linkToPlace" target="_blank" href="/place?placename=Carthage&groupId=441&placeId=820">Carthage</a>, or to go to war with her, because the threat of a Celtic invasion was hanging over them, the attack being indeed expected from day to day.
They decided, then, to smooth down and conciliate Hasdrubal in the first place, and then to attack the Celts and decide the issue by arms, for they thought that as long as they had these Celts threatening their frontier, not only would they never be masters of <a class="linkToPlace" target="_blank" href="/place?placename=Italy&groupId=656&placeId=1199">Italy</a>, but they would not even be safe in <a class="linkToPlace" target="_blank" href="/place?placename=Rome&groupId=935&placeId=1669">Rome</a> itself.
Accordingly, after having sent envoys to Hasdrubal and made a treaty, in which no mention was made of the rest of <a class="linkToPlace" target="_blank" href="/place?placename=Spain&groupId=983&placeId=1735">Spain</a>, but the Carthaginians engaged not to cross the <a class="linkToPlace" target="_blank" href="/place?placename=Ebro&groupId=549&placeId=1031">Ebro</a> in arms, they at once entered on the struggle against the Italian Celts.
