Julius Caesar

, the RubiconAs Suetonius tells it, over a century later

In plain words, ours

At the river that bordered his province, he stopped to think, then said: we can still turn back, but once we cross this little bridge, we have to fight it out.

Coming up with his troops on the banks of the Rubicon, which was the boundary of his province, he halted for a while, and, revolving in his mind the importance of the step he was on the point of taking, he turned to those about him, and said: “We may still retreat; but if we pass this little bridge, nothing is left for us but to fight it out in arms.”

What was going on, our summary

As Suetonius tells it, over a century later: after the tribunes who spoke for Caesar fled Rome, he set off by night and got lost on the way. At the Rubicon, the edge of his province, he stopped. Crossing it with an army, which the law forbade, began a civil war with Pompey and the Senate.

When intelligence, therefore, was received, that the interposition of the tribunes in his favour had been utterly rejected, and that they themselves had fled from the city, he immediately sent forward some cohorts, but privately, to prevent any suspicion of his design; and, to keep up appearances, attended at a public spectacle, examined the model of a fencing-school which he proposed to build, and, as usual, sat down to table with a numerous party of his friends. But after sun-set, mules being put to his carriage from a neighbouring mill, he set forward on his journey with all possible privacy, and a small retinue. The lights going out, he lost his way, and wandered about a long time, until at length, by the help of a guide, whom he found towards day-break, he proceeded on foot through some narrow paths, and again reached the road.

The quote: Coming up with his troops on the banks of the Rubicon, which was the boundary of his province, he halted for a while, and, revolving in his mind the importance of the step he was on the point of taking, he turned to those about him, and said: “We may still retreat; but if we pass this little bridge, nothing is left for us but to fight it out in arms.”

While he was thus hesitating, the following incident occurred. A person remarkable for his noble mien and graceful aspect, appeared close at hand, sitting and playing upon a pipe. When, not only the shepherds, but a number of soldiers also flocked from their posts to listen to him, and some trumpeters among them, he snatched a trumpet from one of them, ran to the river with it, and sounding the advance with a piercing blast, crossed to the other side. Upon this, Caesar exclaimed, “Let us go whither the omens of the Gods and the iniquity of our enemies call us.
