Vicksburg is a dramatic account of the Confederate Army's attempts to capture the fortress of Vicksburg from October 1862 to July 1863, with a particular emphasis on the generalship of John C. Pemberton, the commander of the Confederate Army of Mississippi.
On July 4, 1863, Confederate Lieutenant General John C. Pemberton surrendered Vicksburg and the Army of Mississippi to Ulysses S. Grant. Pemberton was immediately denounced as a poor general, whose incompetence and indecision cost the South control of the impregnable fortress. Some Southern newspapers were especially harsh, pointing out that Pemberton was a Northerner (he was born in Philadelphia) and suggesting that treachery was behind the fall of "the Confederate Gibraltar."
He was thoroughly lambasted as being a bungling fool, a poor leader and a hopeless general. Historians have generally followed suit. Forgotten in all of this is the fact that Grant attempted to take or bypass Vicksburg nine times. In five of these attempts, he was fought to a standstill and sometimes convincingly defeated by none other than John C. Pemberton, who was outnumbered two to one and sometimes more. This is the incredible story of the Fall of Vicksburg.

The endgame for Hitler’s Reich Hitler’s army had dared all to win all on the Western Front with its surprise winter campaign in the Ardennes, the “Battle of the Bulge”. But when American and Allied forces recovered from their initial shock, the German Army, the Wehrmacht, was left fighting for its very survival - especially on the Eastern Front, where the Soviet Army was intent on matching, or even surpassing, Nazi atrocities. At the mercy of the Fuhrer - who refused to acknowledge reality and insisted on forbidding German retreats - the Wehrmacht was slowly annihilated in horrific battles that have rarely been adequately covered in histories of the Second World War, perhaps most especially the brutal Soviet siege of Budapest, which became known as “the Stalingrad of the Waffen-SS”. Now, at last, veteran military historian Dr. Samuel Mitcham, in the capstone of a career covering of more than 40 books - most of them on the German Armed Forces in World War II - tells the extraordinary tale of how Hitler’s once-feared war machine came to a cataclysmic end, from the Battle of the Bulge in December 1944 to the German surrender in May 1945. Making use of German wartime papers and memoirs - some rarely seen in English-language sources - Mitcham’s sweeping narrative makes The Death of Hitler’s War Machine: The Final Destruction of the Wehrmacht a book that needs to be in the hands of of every student of World War II history.
