So answered those strange horsemen, And each couched low his spear； And forthwith all the ranks of Rome Were bold, and of good cheer： And on the thirty armies Came wonder and affright, And Ardea wavered on the left, And Cora on the right. ``Rome to the charge！'' cried Aulus； ``The foe begins to yield！ Charge for the hearth of Vesta！ Charge for the Golden Shield！ Let no man stop to plunder, But slay, and slay, and slay； The gods who live forever Are on our side to-day.''
