In 1397, as a result of the Sack of Torreblanca,[1] in which Tlmeceni pirates captured the consecrated host [2] and 108 prisoners,[3] King Martin of Aragon ordered a retaliatory attack on Dellys also known as Tedelis,[4][5] chartering a fleet led by Joan Gascó[6] and an army led by Jaume de Pertusa.

[7] The fleet gathered in Ibiza, amassing a total force of 70 ships and 7,500 crusaders.

[3] The fleet set sail in August 1398, and successfully reached Dellys, which was sacked, killing around 1,000 villagers.

[8] However, the fleet could not cross the Rhône due to low water levels and directly provide aid, though they did manage to grant a three-month truce for the besieged.

[2] The following year, Martin ordered a repeat of the campaign, this time, directed at Bona.
