They passed on in this manner over plains, and across rivers, and through mountain passes, until at length they reached the heart of Thessaly.
Here at last the armies came to a stand and fought the final battle.
[Illustration: ROMAN STANDARD BEARERS.] [Sidenote: The plain of Pharsalia.] [Sidenote: Roman standard bearers.] [Sidenote: Pompey draws up his army.] [Sidenote: Forces on both sides.] The place was known then as the plain of Pharsalia, and the greatness of the contest which was decided there has immortalized its name.

Pompey's forces were far more numerous than those of Caesar, and the advantage in all the partial contests which had taken place for some time had been on his side; he felt, consequently, sure of victory.

He drew up his men in a line, one flank resting upon the bank of a river, which protected them from attack on that side.

From this point, the long line of legions, drawn up in battle array, extended out upon the plain, and was terminated at the other extremity by strong squadrons of horse, and bodies of slingers and archers, so as to give the force of weapons and the activity of men as great a range as possible there, in order to prevent Caesar's being able to outflank and surround them There was, however, apparently very little danger of this, for Caesar, according to his own story, had but about half as strong a force as Pompey.

The army of the latter, he says, consisted of nearly fifty thousand men, while his own number was between twenty and thirty thousand.
