According to popular legend, Montbars' legendary hatred of the Spanish came from reading about the cruelties of the Conquistadors upon the New World,[2][3][4][5] particularly a narrative describing atrocities carried out against the native Indians, written by Las Casas.

He looted and set fire to Porto Caballo, San Pedro, Venezuelan Gibraltar and Maricaibo, among other Spanish strongholds, and captured or destroyed numerous other forts and settlements.

One of his more infamous methods was to cut open the abdomen of one of his prisoners, extract one end of the large intestine and nail it to a post, then force the man to "dance to his death by beating his backside with a burning log".

Christine Biccah Montauban and her son were rescued by Roche Braziliano, a friend and fellow member of Buccaneers Brotherhood, after an attempt of executing Daniel Montbars by the Spanish Fleet.

He and members of his crew reportedly buried their fortune near Anse du Gouverneur[10] or Grande Saline on Saint Barthelemy, although Montbars was said to have died before he could come back for his treasure.
