The Battle of Britain could not stop Operation Sealion, the planned German invasion. The historians got it wrong. This is a big claim to make, yet the reasoning behind it is remarkably straightforward. In Invasion 1940, author Derek Robinson asks why historians have dovetailed the Battle of Britain with Operation Sealion. Military experts say the Battle prevented an invasion, but they don't exactly explain how. Why is it taken for granted that an air battle could halt an assault from the sea? The skill and courage of the RAF pilots isn't in question, but did the Luftwaffe's failure to destroy them, plus bad weather, really persuade Hitler to cancel Sealion? That's what Hitler said, and Churchill claimed a great victory for 'The Few'. The Battle of Britain ended; Sealion died. One followed the other, so the first must have caused the second. But Derek Robinson challenges that assumption and reaches a startling conclusion. The real obstacle to invasion was a force that both Churchill and Hitler failed to acknowledge.In this fascinating reexamination, Robinson doesn't seek to downplay the heroism and achievements of the RAF; rather, he wants the true picture of that brilliant moment in history--Invasion, 1940-- to emerge.

Set during the height of World War I in January 1918, Goshawk Squadron follows the misfortunes of a British flight squadron on the Western Front. For Stanley Woolley, commanding officer of Goshawk Squadron, the romance of chivalry in the clouds is just a myth. The code he drums into his men is simple and savage: shoot the enemy in the back before he knows you're there. Even so, he believes the whole squadron will be dead within three months. A monumental work at the time of its original release, Booker-shortlisted Goshawk Squadron is now viewed as a classic in the mode of Catch 22. Wry, brutal, cynical and hilarious, the men of Robinson's squadron are themselves an embodiment of the maddening contradictions of war: as much a refined troop of British gentleman as they are a viscous band of brothers hell-bent on staying alive and winning the war.

This book is a study of group theoretical properties of two dis­ parate kinds, firstly finiteness conditions or generalizations of fini­ teness and secondly generalizations of solubility or nilpotence. It will be particularly interesting to discuss groups which possess properties of both types. The origins of the subject may be traced back to the nineteen twenties and thirties and are associated with the names of R. Baer, S. N. Cernikov, K. A. Hirsch, A. G. Kuros, 0.]. Schmidt and H. Wie­ landt. Since this early period, the body of theory has expanded at an increasingly rapid rate through the efforts of many group theorists, particularly in Germany, Great Britain and the Soviet Union. Some of the highest points attained can, perhaps, be found in the work of P. Hall and A. I. Mal'cev on infinite soluble groups. Kuras's well-known book "The theory of groups" has exercised a strong influence on the development of the theory of infinite groups: this is particularly true of the second edition in its English translation of 1955. To cope with the enormous increase in knowledge since that date, a third volume, containing a survey of the contents of a very large number of papers but without proofs, was added to the book in 1967.
