     And while our soldiers were hesitating [to attempt coming ashore], especially due to the depth of the sea, the man who carried the eagle of the Tenth Legion, after calling upon the gods to witness that the battle might turn out favorably for the legion, exclaimed: “Jump down, fellow soldiers, unless you wish to betray your eagle to the enemy; I, certainly, shall have done my duty to the republic and my commander!”
