Such were the sons of Giovanni-Galeazzo Visconti, the half-brothers of the gentle Valentina of Orleans. When she sank broken-hearted into an early grave--her husband unavenged, her children unprotected--she felt how hopeless it would be to look for succor or sympathy to her father's house; yet her last moments were passed in peace. Her maternal solicitude for her defenseless orphans was soothed by the conviction that they would be guarded and protected by one true and faithful friend. Their magnanimous and high-minded mother had attached to them, by ties of affection and gratitude more strong, more enduring than those of blood, one well fitted by his chivalrous nature and heroic bravery to defend and shelter the children of his protectress. Dunois--"the young and brave Dunois"--the bastard of Orleans, as he is generally styled, was the illegitimate son of her husband. Valentina, far from slighting the neglected boy, brought him home to her, nurtured and educated him with her children, cherishing him as if he had indeed, been the son of her bosom. If the chronicles of the time are to be believed, she loved him more fondly than her own offspring. "My noble and gallant boy," she would say to him, "I have been robbed of thee; it is thou that art destined to be thy father's avenger; wilt thou not, for my sake, who have loved thee so well, protect and cherish these helpless little ones?" Long years after the death of Valentina the vengeance of heaven did overtake Jean-sans-peur of Burgundy: he fell the victim of treachery such as he had inflicted on Louis of Orleans; but the cruel retaliation was not accomplished through the instrumentality or connivance of the Orleanists: Dunois was destined to play a far nobler part. The able seconder of Joan of Arc--the brave defender of Orleans against the besieging English host--he may rank next to his illustrious countrywoman, "La Pucelle," as the deliverer of his country from foreign foes. His bravery in war was not greater than his disinterested devotion to his half-brothers. Well and nobly did he repay to Valentina, by his unceasing devotion to her children, her tender care of his early years. Charles of Orleans, taken prisoner by the English at the fatal battle of Agincourt, was detained for the greater part of his life in captivity: his infant children were unable to maintain their rights. Dunois reconquered for them their hereditary rights, the extensive appanages of the house of Orleans. They owed every thing to his sincere and watchful affection.
