Res Gestae

Come, then, to share in pains and perils, and undertake the charge of defending Gaul, ready to relieve the afflicted regions with every bounty. And if it becomes necessary to engage with the enemy, take your place with sure footing amid the standard-bearers themselves; be a thoughtful advisor of daring in due season, animate the warriors by taking the lead with utmost caution, strengthen them when in disorder with reinforcements, modestly rebuke the slothful, and be present as a most faithful witness at the side of the strong, as well as of the weak.

Therefore, urged by the great crisis, go forth, yourself a brave man, ready to lead men equally brave. We shall stand by each other in turn with firm and steadfast affection, we shall campaign at the same time, and together we shall rule over a pacified world, provided only God grants our prayers, with equal moderation and conscientiousness. You will seem to be present with me everywhere, and I shall not fail you in whatever you undertake. In fine, go, hasten, with the united prayers of all, to defend with sleepless care the post assigned you, as it were, by your country herself.
