The breaking of the Enigma machine is one of the most heroic stories of the Second World War and highlights the crucial work of the codebreakers of Bletchley Park, which prevented Britain's certain defeat in 1941. But there was another German cipher machine, used by Hitler himself to convey messages to his top generals in the field. A machine more complex and secure than Enigma. A machine that could never be broken. For sixty years, no one knew about Lorenz or 'Tunny', or the determined group of men who finally broke the code and thus changed the course of the war. Many of them went to their deaths without anyone knowing of their achievements. Here, for the first time, senior codebreaker Captain Jerry Roberts tells the complete story of this extraordinary feat of intellect and of his struggle to get his wartime colleagues the recognition they deserve. The work carried out at Bletchley Park during the war to partially automate the process of breaking Lorenz, which had previously been done entirely by hand, was groundbreaking and is recognised as having kick-started the modern computer age.
This is the dynamic account of one of the most destructive maritime actions to take place in Connecticut history: the 1814 British attack on the privateers of Pettipaug, known today as the British Raid on Essex. During the height of the War of 1812, 136 Royal marines and sailors made their way up the Connecticut River from warships anchored in Long Island Sound. Guided by a well-paid American traitor the British navigated the Saybrook shoals and advanced up the river under cover of darkness. By the time it was over, the British had burned twenty-seven American vessels, including six newly built privateers. It was the largest single maritime loss of the war. Yet this story has been virtually left out of the history books--the forgotten battle of the forgotten war. This new account from author and historian Jerry Roberts is the definitive overview of this event and includes a wealth of new information drawn from recent research and archaeological finds. Lavish illustrations and detailed maps bring the battle to life.

From live productions of the 1950s like Requiem for a Heavyweight to big budget mini-series like Band of Brothers, long-form television programs have been helmed by some of the most creative and accomplished names in directing. Encyclopedia of Television Film Directors brings attention to the directors of these productions, citing every director of stand alone long-form television programs: made for TV movies, movie-length pilots, mini-series, and feature-length anthology programs, as well as drama, comedy, and musical specials of more than 60 minutes. Each of the nearly 2,000 entries provides a brief career sketch of the director, his or her notable works, awards, and a filmography. Many entries also provide brief discussions of key shows, movies, and other productions. Appendixes include Emmy Awards, DGA Awards, and other accolades, as well as a list of anthology programs. A much-needed reference that celebrates these often-neglected artists, Encyclopedia of Television Film Directors is an indispensable resource for anyone interested in the history of the medium.
