The increased resistance of masonry had at an early period induced artillerymen to obtain a flank fire, and we also find Albert Durer and Leonardo da Vinci had studied the advantages resulting from the ricochet of shot. But Vauban was the first to unite the two, so as to create a formidable system of attack. Throwing up his batteries on the flank of a bastion, he lessened the charge and elevated the guns so that the shot went just clear of the enemy's parapet and dropped within their works, of a face and disabled its guns. The effect of this simple idea was to cause perfect consternation, not only in the minds of engineers, but also in that of governments. The former were vexed that their numerous self-supporting fronts, well strengthened with cannon, should be rendered useless by shot hopping along and destroying their armaments, and they proposed various ineffectual remedies; amongst others earthern mounds at certain intervals, called "traverses," but shells were then used and the traverses destroyed. Further than this, however, the evil could not be remedied, for all these suggestions cost money. In the preceding century the erection of the citadel of Antwerp had cost upwards of 1,400,000 florins, and the fortifications of such towns as Malines or Orleans averaged about 5,000,000 florins. Since then the various improvements introduced ran up a front of fortification of four hundred yards in length to some 40,000/., and the alterations proposed by Vauban to counteract his own plan of attack doubled that sum. Yet was he economical compared to many who attempted to improve on his alterations. It is not my intention to investigate the numerous theories brought forward by men skilled in military science for this purpose, nevertheless I shall...
Description : "I've had many faces. Many lives. I don't admit to all of them. There's one life I've tried very hard to forget-the Doctor who fought in the Time War." The Great Time War has raged for centuries, ravaging the universe. The Daleks and the Time Lords deploy ever more dangerous weapons in desperate attempts at victory, but there is no end in sight. On the outer rim of the Tantalus Eye, scores of human colony planets are now overrun by Dalek occupation forces. A weary, angry Doctor leads a flotilla of Battle TARDISes against the Dalek stronghold but in the midst of the carnage, the Doctor's TARDIS crashes to a planet below: Moldox. As the Doctor is trapped in an apocalyptic landscape, Dalek patrols roam amongst the wreckage, rounding up the remaining civilians. But why haven't the Daleks simply killed the humans? Searching for answers, the Doctor meets 'Cinder', a young Dalek hunter. Their struggles to discover the Dalek plan take them from the ruins of Moldox to the halls of Gallifrey and set in chain events that will change everything. And everyone.
Description : Engines of War tells the dramatic story of how the railways revolutionized the nature of warfare, ushering in an age of industrialized conflict in which wars were fought on a previously unimaginable scale. From the moment of its first appearance, the 'iron road' not only rendered armies more mobile, but also massively increased the power and the deadliness of the weaponry available to them. Christian Wolmar's epic account of how an invention that brought prosperity in peace-time metamorphosed in time of war into a weapon of death, is counterpointed by a wealth of human stories of personal endeavour and private tragedy. Embracing every major conflict in which railways have played a part - the Crimean War, the American Civil War, the First and Second Boer Wars, the two World Wars, the Korean War and the Cold War, Engines of War is awe-inspiring tale of industrial might and the transformative power of machinery.
Description : This book explores the nature of creativity in engineering and technology, and how it relates to creativity in art or science. Lienhard has for ten years done a twice-weekly radio show, carried on about 35 NPR stations, consisting of 3-minute essays on technology. He uses the substance of selected segments of his radio program to create a continuous narrative presenting his insights on technological creativity. This book has the same title as his radio program, to further draw the attention of his one million listeners.
Description : Artillery Through the Ages is a short illustrated history of cannon, emphasizing types used in America. Many of the types of cannon described in this booklet may be seen in areas of the National Park System throughout the U.S. Looking at an old-time cannon, most people are sure of just one thing: the shot came out of the front end. For that reason these pages are written; people are curious about the fascinating weapon that so prodigiously and powerfully lengthened the warriors arm. And theirs is a justifiable curiosity, because the gunner and his "art" played a significant role in our history.
