Ch IX, p210:  "In May [Stephen] had an interview with Louis VI of France, and was recognized by him as duke, on the same terms as Henry I had been, his son Eustace doing homage in his stead..."
Ch X, p229:  "...During the summer Stephen gained an advantage in securing the hand of Constance, the sister of Louis VII of France, for his son Eustace, it was believed at the time by a liberal use of the teasures of Bishop Roger."
Ch XI, p248:  "...By the end of June the young bridegroom was at Barfleur preparing to cross the channel with an invading force. But he was not to be permitted to enjoy his newfortunes unchallenged. Louis VII in particular had reasons for interfering, and the law was on his side. The heiress Eleanor had no right to marry without the consent of her feudal suzerain. A summons, it is said, was at once served on Henry toappear before the king's court and answer for his conduct, and this summons, which Henry refused to obey, was supported by a new coalition. Louis and Eustace were again in alliance, and they were joined by Henry's own brother Geoffrey, who could make considerable trouble in the south of Henry's lands, by Robert of Dreux, Count of Perche, and by Eustace's cousin Henry, Count of Champagne. Stephen's brother Theobald had died at the beginning of the year, and his great dominions had been divided, Champagne and Blois being once more separated, never to be reunited until they were absorbed at different dates into the royal domain..."
p251:  "...From Wallingford also, Eustace withdrew from his father, greatly angered by the truce which had been made, and went off to the east on an expedition of his own which looks much like a plundering raid. Rashly he laid waste the lands of St Edmund, who was well known to be a fierce protector of his own and to have nohesitation at striking even a royal robber. Punishment quickly followed the offence. Within a week Eustace was smitten with madness and died on August 17, a new and terrible warning of the fate of the sacrilegious. This death changed the wholeoutlook for the future. Stephen had no more interest in continuing the war than to protect himself. His wife had now been dead for more than a year. His next son, William, had never looked forward to the crown, and never been prominent in thestruggle..."
A History of the Plantagenets, Vol I, The Conquering Family, Thomas B Costain, Doubleday & Co, Garden City, 1949, p13:
"In the meantime Queen Matilda took her youthful son Eustace to France and negotiated a marriage between the boy and the Princess Constance, sister of Louis VII, in the hope of cementing an alliance."

Encyclopaedia Britannica, 1981, Micropaedia, Vol IX, p555, Stephen: "[Stephen] hoped only to secure the succession for his son, Eustace,but to do so he had to deal with Matilda's son, Henry of Anjou, who invaded England in Jan 1153 to claim his royal inheritance. When Eustace died in August, Stephen lost heart; he signed a treaty designating Henry as his successor. At Stephen's death Henry ascended the throne as King Henry II."
