The frightened monarch was not slow in taking this advice. Leaving a strong force in Greece, under the command of his general Mardonius, he marched with the speed of fear for the bridge. But he had nearly exhausted the country of food in his advance, and starvation and plague attended his retreat, many of the men being obliged to eat leaves, grass, and the bark of trees, and great numbers of them dying before the Hellespont was reached. Here he found the bridge gone. A storm had de- stroyed it. He was forced to have his army taken across in ships.
