Gisbert Brom, Catholic Encyclopedia (1913)
“ Alva was, as even Motley in "The Rise of the Dutch Republic" (London, 1868, 9, 336) , admits, "the most successful and experienced general of Spain, or of Europe, in his day. No man had studied military science more deeply, or practiced it more constantly." In sixty years of military service he was never surprised, never defeated. He excelled in slow and prudent tactics, deeming that nothing was so uncertain as victory. He stands amongst the greatest generals of history. ”
