Clad in metal armor and chains, the natives did not believe that these creatures were dogs and regarded them as beasts. These attack dogs, often wearing their own armor, were the common European shock and awe tactic of the period. The first documented New World use of these canine swat teams occurred in 1495 when Bartholomew Columbus, Chris’s brother, used 20 mastiffs in a battle waged at Santa Maris el Antigua, Darien with his brother employing the same approach a year later. These dogs were trained to pursue, disembowel and dismember humans and to this purpose, enjoyed a human diet in the Americas. The Spanish reveled in holding human hunts called “la Monteria infernal “where much sport was made of chasing and killing the local men, women and children. The noted Spanish apologist Bartolme de La Casas has left us numerous accounts of the exploits of these hounds from hell and it is easy to understand why these horrific memes still prevail in the cultures of Latin America. The names of many of these dogs so esteemed by the Spaniards still live on and here are but a few:
Bercerruillo the terror of Borinquen, until he was fallen by 50 arrows, received a salary one and a half times that of an archer from his owner Ponce de Leon.
Leoncillo (Little Lion), Bercerruillo’s son, was Balboa’s warrior, earned over 500 gold pesos in booty during his many campaigns, and he was the first Western dog to see the Pacific. When ordered to catch a native he would grab the man’s arm in his mouth. If the man came along quietly, they walked slowly to Balboa. If there was any resistance, the dog ripped him apart.
Bruto, De Soto’s champion, received 20 slaves as spoils before his career ended.
