“ In the summer of the year 42 B. C., Antony led a division of the joint army of the triumvirate across the sea and through Macedonia, followed soon after by Octavius with additional forces. They were met at Philippi, and there, in two great battles, fought with an interval of twenty days between, the republic of Rome was finally done to death. "The battle of Philippi, in the estimation of the Roman writers, was the most memorable conflict in their military annals. The numbers engaged on either side far exceed all former experience. ”
