From the back of the book:
""Husband, in honor of our marriage, in addition to this cake, I give to you a regiment of BattleMechs and the means to support them in perpetuity," spoke Melissa Steiner of the Lyran Commonwealth after her wedding to Hanse Davion.
"I thank you for the gift, beloved," began the Prince of the Federated Suns. He lifted a piece of cake in his right hand. "Wife, in honor of our marriage, in addition to this morsel, I give you a vast prize. Here, my love, I give you the Capellan Confederation!"
Wedding vows were taken, alliances were made, and the forces of Davion launched an all-out assault on the Capellan Confederation. All-out war in the Inner Sphere soon followed, beginning the cataclysmic struggle of the 4th Succession War.
This history examines the war in strategic terms. The campaigns, the tactics, and the battles, compiled from reports by the commanders and MechWarriors themselves.
Full-color maps depict the movement of forces, battlefield terrain, and the cities and other objectives they fought for. BattleForce statistics are included for over 30 key regiments, such as Wolf's Dragoons. Hundreds of BattleTech engagements can be generated from these stats using a simple conversion table."
