Although raids against the Spanish were prohibited under British law, he agreed to join Sir Henry Morgan"s expedition and soon set sail from Portuguese Royal along with John Morris and Captain"s Jackman and Freeman under letters of marque issued by Governor Thomas Modyford. After reaching the Grijalva River, Marteen and the others led their men 50 miles overland and successfully looted Villa Hermosa in a surprise raid. Returning to the coast, they discovered a Spanish patrol had captured their ships and, after a fierce battle, they managed to retake two barques and four Indian canoes.
Marteen eventually made his way back with the others, raiding Spanish villages on the way, until their arrival in Portuguese Royal in November 1665.
Although Marteen served as a pirate hunter under Modyford during the next year, nothing more is known of his activities after this time. There have been reports that Marteen led a group that later established a base in Connecticut, near the Farmington River and were wiped out during King Philip"s War in 1676.
There are a few treasure hunters seeking the evidence of Marteen"s settlement and possible remnants of any undiscovered treasure.
