Joseph had but about twenty thousand troops in the vicinity of Cadiz, with which force he could be but little more than a spectator of events as they should occur. Wellington had a highly-disciplined army of sixty thousand men, independent of the guerrilla bands whom he could summon to his aid. CHAPTER X.

Joseph was much embarrassed. Should he leave his scattered forces in the south of Spain, there was danger that they would be attacked and destroyed piecemeal by Wellington. Should he withdraw them, and concentrate his forces in the north, the whole south of Spain would be instantly overrun by the English, and Joseph would lose one-half of his kingdom. His total force in Spain, garrisoning the forts and composing his detached bands in the south, the centre, the north, and the west, amounted to a little over two hundred and thirty thousand men.
