A first-hand account of the defense of Outpost Harry, a strategic position in Korea’s Chorwon Valley brutally contested by the US and Chinese armies as they jockeyed for advantageous positions in anticipation of peace negotiations in Panmunjom. Evans recounts these last days of the war and savage battles for control of important local terrain features against a determined Chinese assault.By June 1953 the Korean War, marked at the outset by extremely fluid advances and retreats up and down the peninsula, had settled into position warfare very near the original pre-war demarcation line between North and South Korea. At this point both sides were fighting to win a peace, to achieve incremental advantages that could be translated into gains at the peace negotiations in Panmunjom. The battle at Outpost Harry devolved into hand-to-hand combat during a period of constant, intense fighting that lasted two days. The author, although seriously wounded that night, refused evacuation and remained on the hill to successfully lead his company in defense of the outpost. It wasn’t romantic; it wasn’t chivalrous; and many died or were badly wounded. Some of the survivors never fully overcame the mental and physical damage they suffered during the nightmare.With this book, one of those scarred by that experience recounts the events of the battle and his lifelong efforts to deal with the residual horrors. The Korean Conflict may be called "the forgotten war" by some, but not by those who were on the front lines.

From the prediction of complex weather patterns to the design of swimsuits, modeling has, over the years, quietly but steadily become an essential part of almost every field and industry—and steelmaking is no exception. Factors such as visual opacity, high operating temperature, and the relatively large size of industrial reactors often preclude direct experimental observation in steel manufacturing. Therefore the industry is overwhelmingly dependent on modeling to quickly and cost-effectively provide insight into analysis, design, optimization, and control of processing. However, few, if any, books offer the adequate coverage of modeling.Addresses Fundamental Principles of Physical and Mathematical Modeling in Steelmaking ProcessesModeling of Steelmaking Processes meets that ever-present demand and provides a solid knowledge base on which to build. With content designed to serve professionals and students, this book starts with an overview of steelmaking and develops into a focused description of underlying scientific fundamentals and applications. This powerful learning tool: Presents an overview of steelmaking, the relevance of modeling and measurements, the evolution of steelmaking, and modern technologyDiscusses emerging issues, such as environmental emissions, recycling, and product development and qualityReviews computational fluid dynamics (CFD) softwareAnalyzes mechanistic, AI-based, and macroscopic models, to provide a holistic view of steelmaking process modelingProvides useful questions and problems, as well as a practice session on modeling, to reinforce understandingDeveloped as a self-tutorial, this text explores thermodynamic principles, analysis of metallurgical kinetics and transport phenomena, and key numerical methods, helping readers easily navigate a generally complex subject.
