Pages on the geology & oceanography in the first chapter were fascinating: the rock is composed of the shells of billions and billions of organisms; Neanderthal man ought to be called Gibraltar woman, the first skull having been found there; the Med constantly evaporating because river inflow too low pulls a surface current in from the Atlantic to replenish the basin, and the higher salinity causes a subsurface current out; caverns full of stalactites and stalagmites, terrifying to early travelers, some early sailor’s report of which contributed to the episode of Odysseus’ visit to the land of the dead?
British ownership of the Rock, a costly controversial affair, paid off handsomely in WWII. This book is very much like dinner with a retired admiral, centuries of campaigns illustrated with walnuts and cutlery over Port. But it is much more and the cultural, sociological & political history and the personality sketches, with quotations from letters & diaries, are as interesting as the military details.
