The German A7V and the British Mark IV were similar in weight, size, and speed, but differed significantly in armour, armament and maneuverability. The A7V had thicker armour, and had nearly double the horsepower per ton. The Mark IV's pair of side-mounted 6pdr cannons forced the vehicle to present its side arc to an enemy in order to fire one of its main guns. Possessing twice as many machine guns as the Mark IV, the A7V had a frontally mounted 57mm gun that proved capable of defeating the Mark IV's armour. The Mark IV's rhomboid design proved superior in crossing trenches, climbing obstacles and moving over rough terrain. As the first tank-versus-tank engagement in history, the fighting around Villers-Bretonneux showcased the British Mark IV and German A7V designs. Although not purpose-built to combat enemy armour, both vehicles proved the viability of such operations, which during the postwar period led to key advances in suspension, armour, gunsights, ammunition, and command and control. While the British continued to develop their armoured forces, German armour development never materialized, and only in the postwar period did they address the issue.

The Allies' M10 Tank Destroyer and the Germans' Sturmgeschütz (StuG) lll were the unsung workhorses of the northwest European battlefields of 1944–45. While their mission was not principally fighting one another, their widespread use ensured their frequent encounters, from the Normandy Bocage, to the rubble-strewn streets of Aachen. The StuG lll was the quintessential assault gun, a low-slung, heavily armoured, turret-less vehicle intended to provide direct fire support for infantry formations, whilst the M10 3in Gun Motor Carriage was originally developed as a tank destroyer. However, by 1944 the 3in gun proved ineffectual against the most thickly armored German tanks, and was consequently relegated to infantry support too. Widely deployed in roles their designers had not envisaged, these two armoured fighting vehicles clashed repeatedly during the 11-month campaign, which saw the Allies advance from Normandy to the heart of the Reich. Fully illustrated with specially commissioned artwork, this is the story of their confrontation at the height of World War ll.

Within months of the start of the First World War, Germany began to run out of the raw materials it needed to make explosives. As Germany faced imminent defeat, chemists such as Fritz Haber and Carl Bosch came to the rescue with Nobel Prize winning discoveries that overcame the shortages and enabled the country to continue in the war. Similarly, Britain could not have sustained its war effort for four years had it not been for chemists like Chaim Weizmann who was later to become the first president of the State of Israel. Michael Freemantle tells the stories of these and many other chemists and explains how their work underpinned and shaped what became known as The Chemists’ War. He reveals: • how chemistry contributed to the care of the sick and wounded and to the health and safety of troops; • how coal not only powered the war but was also an important source of the chemicals needed for the manufacture of explosives, dyes, medicines and antiseptics; • how Britain’s production of propellants relied on the slaughter of tens of thousands of whales; • how a precious metal played a critical role in the war; • how poisonous chemicals were used as weapons of mass destruction for the first time in the history of warfare and how chemists developed gas masks for protection against these weapons; • how the British naval blockade of Germany imperilled agricultural production in the United States. The book will appeal to the general reader as well as the many scientists and historians interested in the Great War.

The Indo-Pakistani War of 1965 witnessed some of the largest tank battles since World War II, notably between India's British-made Centurion Mk 7s and the American-made M48 Pattons fielded by Pakistan. The two countries' tank regiments, many of which shared a proud legacy in the British Indian Army, fought one another in the difficult terrain of Jammu and Kashmir, the focus of a long-running dispute between India and Pakistan. The armoured clashes at Asal Uttar, Chawinda and Phillora would demonstrate that the Centurion, with its powerful gun and lower profile, generally proved superior to the faster, lighter but overly complex Patton. Featuring full-colour artwork, expert analysis and archive photographs, this is the full story of the clash between two leading tanks of the Cold War era that were never designed to fight each other, but rather to line up on battlefields as allies.

In the Age of Fighting Sail (1650–1820), ambitious officers of the navies of many nations sought command of a frigate. Speedy, nimble and formidably armed, frigates often operated independently, unlike the larger ships of the line. Legendary sailors such as Edward Pellew and Charles-Alexandre Léon Durand, Comte de Linoise, found that commanding such a ship offered numerous opportunities for wealth. In this book, four representative frigate duels are examined: first, a battle fought between two closely matched ships (HMS Nymphe (36) vs La Cléopâtre (32); second, a victory won by an inferior British frigate over a superior French frigate (HMS Pallas (32) vs Minerve (40); third, a victory – the only one – by an inferior French frigate over a superior British frigate (HMS Ambuscade (32) vs Baïonnaise (24), and fourth, victory of a superior British frigate over an inferior French frigate (HMS Indefatigable (44) of Hornblower fame vs La Virginie (40). Featuring specially commissioned artwork and offering expert analysis, this study provides a vivid account of the bloody combats fought by the most romantic warship of the Revolutionary and Napoleonic era – the frigate.
