The Queen of the Savannah by Gustave Aimard

Although since the beginning of the civil war the Hacienda del Barrio had frequently served as headquarters for the insurgents of New Spain, and, for this reason, had sustained several regular sieges from the government troops, who twice took it by storm, still, in the interior at least, but slight changes had taken place since the time when we first introduced the reader to it.

Still this house, which at that time was almost a country mansion, had become a real fortress, a deep and wide fosse had been dug round that side of the walls which might be accessible, and the threatening muzzles of several heavy guns peeped out of the embrasures, to avoid a surprise and defend the approaches to the hacienda. The trees had been felled for a radius of nearly a mile all round, the scarped path which ran round the hill and led to the gateway had been dug up in several places so as to render the approach still more difficult, and the drawbridge had been placed in working order.
