Dionysius of Halicarnassus, Roman Antiquities 2.36
 Romulus, having attended to these matters, led out his army against the Crustumerians, who were better prepared than the armies of the other cities had been. And after he had reduced them both in a pitched battle and in an assault upon their city, although they had shown great bravery in the struggle, he did not think fit to punish them any further, but made this city also a Roman colony like the two former. 2 Crustumerium was a colony of the Albans sent out many years before the founding of Rome. The fame of the general's valour in war and of his clemency to the conquered being spread through many cities, many brave men joined him, bringing with them considerable bodies of troops, who migrated with their whole families. From one of these leaders, who came from Tyrrhenia and whose name was Caelius, one of the hills, on which he settled, is to this day called the Caelian. Whole cities also submitted to him, beginning with Medullia, and became Roman colonies. 3 But the Sabines, seeing these things, were displeased and blamed one another for not having crushed the power of the Romans while it was in its infancy, instead of which they were now to contend with it when it was greatly increased. They determined, therefore, the make amends for their former mistake by sending out an army of respectable size. And soon afterwards, assembling a general council in the greatest and most famous city in the nation, called Cures, they voted for the war and appointed Titus, surnamed Tatius, the king of that city, to be their general. After the Sabines had come to this decision, the assembly broke up and all returned home to their several cities, where they busied themselves with their preparations for the war, planning to advance on Rome with a great army the following year.
