This invader was very cautious and avoided much of our security.
That peril did not cease till the defeat of the last formidable African invader at the battle of the Rio Salado in 1340.
The Russians slowly retired before the invader, burning and destroying everything in his path.
First, however, Charles cleared Livonia of the invader (July 1701), subsequently occupying the duchy of Courland and converting it into a Swedish governor-generalship. In January 1702 Charles established himself at Bielowice in Lithuania, and, after issuing a proclamation declaring that "the elector of Saxony" had forfeited the Polish crown, set out for Warsaw, which he reached on the 14th of May.
Under his direction the popular rising against the invader ultimately proved triumphant.
