London, 15 September 1940. The air battle over Britain on that day saw two of the most advanced fighter planes, the British Supermarine Spitfire and the German Messerschmitt Bf 109, battle for supremacy of the skies. The Decisive Duel tells the stories of these iconic, classic aircraft and the people that created them: Willy Messerschmitt, the German designer with a love for gliders and admiration for Hitler; R.J. Mitchell, his brilliant British counterpart, who struggled against illness to complete the design of the Spitfire. In fascinating detail, David Isby describes the crucial role the two opposed planes played, from the drawing boards to Dunkirk, the Battle of Britain to the final battles over Germany.

The final, gripping, instalment in The Invincibles series. Octavian has revenged Caesar's name, and defeated the pirate Sextus Pompeius, but now he must ensure his complete rule of Rome. He feels the potential of betrayal around every corner: from his wife Livia, to his best friends and allies Maecenas and Agrippa. He needs heirs, and he needs security, but he has the shadow of Mark Anthony breathing down his neck from Egypt. Will Octavian succeed in this, the definitive duel for the Empire of Rome, or will he destroy everything he's achieved in the process?

Launching Osprey's new Fleet series, this is a spectacularly illustrated, concise and comprehensive account of the Imperial Japanese Navy's striking force at the height of its power. The Imperial Japanese Navy (IJN) entered the Pacific War as one of the most formidable navies in the world, and its combat power was concentrated into one force, the Combined Fleet. In the months that followed Pearl Harbor it enjoyed an unrivaled string of victories, shattering American, British, Australian, and Dutch naval forces. This period of expansion and constant victories ended at the Battle of Midway, after which the Combined Fleet was forced onto the defensive. In this book, Mark Stille draws on his decades of IJN research to explain what made the Combined Fleet the fighting force that it was. Packed with superb original artwork, explanatory 3D diagrams and maps, it examines the fleet's doctrine, innovative tactics and powerful warships. It also details the qualities and importance of IJN leadership, logistics, naval infrastructure, and Japan's shipbuilding capability, and gives an account and analysis of the IJN's combat performance during these crucial months – not just in the famous carrier battles, but also exploring lesser-known elements such as IJN amphibious forces and land-based aviation.
