The military discipline which reigned in the camps of Probus was less cruel than that of Aurelian, but it was equally rigid and exact. The latter had punished the irregularities of the soldiers with unrelenting severity, the former prevented them by employing the legions in constant and useful labors. When Probus commanded in Egypt, he executed many considerable works for the splendor and benefit of that rich country. The navigation of the Nile, so important to Rome itself, was improved; and temples, buildings, porticos, and palaces were constructed by the hands of the soldiers, who acted by turns as architects, as engineers, and as husbandmen. ^57 It was reported of Hannibal, that in order to preserve his troops from the dangerous temptations of idleness, he had obliged them to form large plantations of olive-trees along the coast of Africa. ^58 From a similar principle, Probus exercised his legions in covering with rich vineyards the hills of Gaul and Pannonia, and two considerable spots are described, which were entirely dug and planted by military labor. ^59 One of these, known under the name of Mount Almo, was situated near Sirmium, the country where Probus was born, for which he ever retained a partial affection, and whose gratitude he endeavored to secure, by converting into tillage a large and unhealthy tract of marshy ground. An army thus employed constituted perhaps the most useful, as well as the bravest, portion of Roman subjects.

But in the prosecution of a favorite scheme, the best of men, satisfied with the rectitude of their intentions, are subject to forget the bounds of moderation; nor did Probus himself sufficiently consult the patience and disposition of his fierce legionaries. ^60 The dangers of the military profession seem only to be compensated by a life of pleasure and idleness; but if the duties of the soldier are incessantly aggravated by the labors of the peasant, he will at last sink under the intolerable burden, or shake it off with indignation. The imprudence of Probus is said to have inflamed the discontent of his troops. More attentive to the interests of mankind than to those of the army, he expressed the vain hope, that, by the establishment of universal peace, he should soon abolish the necessity of a standing and mercenary force. ^61 The unguarded expression proved fatal to him. In one of the hottest days of summer, as he severely urged the unwholesome labor of draining the marshes of Sirmium, the soldiers, impatient of fatigue, on a sudden threw down their tools, grasped their arms, and broke out into a furious mutiny. The emperor, conscious of his danger, took refuge in a lofty tower, constructed for the purpose of surveying the progress of the work. ^62 The tower was instantly forced, and a thousand swords were plunged at once into the bosom of the unfortunate Probus. The rage of the troops subsided as soon as it had been gratified. They then lamented their fatal rashness, forgot the severity of the emperor, whom they had massacred, and hastened to perpetuate, by an honorable monument, the memory of his virtues and victories. ^63
