In 1347, Cola di Rienzo (Tribune and effective dictator of the city) had Werner von Urslingen executed in Rome, and Konrad von Landau assumed command of the Great Company. On the conclusion (1360) of the Peace of Bretigny between England and France, Sir John Hawkwood led an army of English mercenaries, called the White Company, into Italy, which took a prominent part in the confused wars of the next thirty years. Towards the end of the century the Italians began to organize armies of the same description. This ended the reign of the purely mercenary company, and began that of the semi-national mercenary army which endured in Europe till replaced by the national standing army system. In 1363, Count von Landau was betrayed by his Hungarian soldiers, and defeated in combat, by the White Company's more advanced tactics under commanders Albert Sterz and John Hawkwood. Strategically, the was replaced with the three-soldier, mounted (a , a groom, and a boy); five composed a , five composed a (flag). By that time, the campaigning condottieri companies were as much Italian as foreign: the Astorre I Manfredi's (Company of the Star); a new (Company of St. George) under Ambrogio Visconti; Niccolò da Montefeltro's (Little Hat Company); and the (Company of the Rose), commanded by Giovanni da Buscareto and Bartolomeo Gonzaga.
