The city had to be abandoned on April 26, forty monks were killed in the battle, he himself was one of the few who managed to escape by sea.He was one of the outstanding protagonists in the defense of Acre, the last crusader stronghold in the Holy Land, which had been besieged by the Mamluks under Sultan Al-Ashraf Khalil since April 1291. When the Mamluks entered the city on May 16, Matthew stopped the defenders fleeing to the port, then counter-attacked, pushing the Mamluks back out of the city from the Saint Anthony's Gate. When the city was stormed again on May 18, he fought again in the front line and was killed in the Genoese quarter.
