G. A. Henty 
When London Burned [EPUB ebook] 

Historical novel set in England in the middle of the seventeenth century. The Preface begins: ‘We are accustomed to regard the Reign of Charles II. as one of the most inglorious periods of English History; but this was far from being the case. … the extravagance and profligacy of the Court were carried to a point unknown before or since, forming…-the main cause of the overthrow of the House of Stuart. But, …the nation made extraordinary advances in commerce and wealth, while the valour of our sailors was as conspicuous under the Dukes of York and Albemarle, Prince Rupert and the Earl of Sandwich… and their victories resulted in transferring the commercial as well as the naval supremacy of Holland to this country. In spite of the cruel blows inflicted on the well-being of the country, alike by the extravagance of the Court, the badness of the Government, the Great Plague, and the destruction of London by fire, an extraordinary extension of of our trade occurred during the reign of Charles II.’ Historical novel set in Spain, where the British battled the French in the Napoleonic Wars. The Preface begins: ”As many boys into whose hands the present volume may fall will not have read my last year’s book, With Moore in Corunna, of which this is a continuation, it is necessary that a few words should be said, to enable them to take up the thread of the story. It was impossible, in the limits of one book, to give even an outline of the story of the Peninsular War, without devoting the whole space to the military operations. It would, in fact, have been a history rather than a tale; and it accordingly closed with the passage of the Douro, and the expulsion of the French from Portugal.’ According to Wikipedia: ‘George Alfred Henty (8 December 1832 – 16 November 1902), referred to as G.
