Could a mercenary explain Malta's unnamed commander?

Could an unnamed mercenary explain the uncertain command of Malta's first siege?

A Muslim mercenary is considered very unlikely in this setting because of local religious loyalties, the Aragonese contingent, and the expectation that a victorious convert would have been celebrated.

A mercenary offers another possible explanation for an unnamed commander. The objection focuses on a Muslim mercenary serving in this particular Maltese defence, where local trust and cooperation with Aragonese troops would matter. A commander who converted to Christianity would also have supplied a victory story worth celebrating, making continued silence harder to explain. Enmity toward the Hafsid kingdom is considered as a reason for such service, but the proposed identification remains unconvincing within this interpretation.
