The Swiss were not flattered by the imitation, and the two bodies of mercenaries immediately became bitter rivals over employment and on the battlefield, where they were often opposed during the major European conflict of the early sixteenth century, the Great Italian Wars. Although the Swiss generally had a significant edge in a simple "push of pike", the resulting combat was nonetheless quite savage, and known to Italian onlookers as "bad war". Period artists such as Hans Holbein attest to the fact that two such huge pike columns crashing into each other could result in a maelstrom of battle, with very many dead and wounded on both sides.
