V. On Escaping from Difficult Situations
6When the consul Gaius Duellius was caught by a chain stretched across the entrance to the harbour of Syracuse, which he had rashly entered, he assembled all his soldiers in the sterns of the boats, and when the boats were thus tilted up, he propelled them forward with the full force of his oarsmen. Thus lifted up over the chain, the prows moved forward. When this part of the boats had been carried over, the soldiers, returning to the prows, depressed these, and the weight thus transferred to them permitted the boats to pass over the chain.58
