February 1509 CE
Diu is a critical outpost in the overall spice trade from India.
The Portuguese attempt to establish trade with India will require the breaking of this strongly defended and lucrative trade network.
In addition to enforcing Portuguese rule, the battle is undertaken as a personal issue by Portuguese viceroy Francisco de Almeida to avenge the death of his son Lourenço at the hands of the Mirocem (Amir Husain Al-Kurdi).
He is so enraged at this death that he is supposed to have said, "He who ate the chick must also eat the rooster, or pay for it".
Aware of the danger facing his city, Malik Ayyaz prepares his defense and writes to appease the viceroy, stating that he has the prisoners and how bravely his son had fought, adding a letter from the Portuguese prisoners stating that they are well treated.
The viceroy answers Malik Ayyaz (referred to as Meliqueaz in Portuguese) with a respectful but menacing letter, stating his intention of revenge, that they better join all forces and prepare to fight or he will destroy Diu.
In a double bind—Malik Ayyaz fearing the destruction of his city, and Mirocem beset in it—they face the Portuguese forces.
The Portuguese have eighteen ships commanded by the viceroy, with about fifteen hundred Portuguese soldiers and four hundred local combatants from Cochin.
The Allied side has one hundred ships, but only twelve are major vessels; the rest are small shallow-draft craft.
After detecting the Portuguese, who approach from Cochin to the north, and fearing their technical superiority, the Egyptians decide to take advantage of the port of Diu and its fort, which had its own artillery.
It is therefore decided to stay anchored at the port and await an attack from the Portuguese.
This may also have been due to the training of the Egyptians, who are used to the more sheltered bays in the Mediterranean, where they also rely upon land-based artillery reinforcements to defeat the enemy.
The Portuguese start the battle with a massive naval bombardment using their on board artillery, followed by hand-to-hand combat in the harbor of Diu.
These Portuguese ships have guns of greater caliber, wielded bybetter artillery crews, and rre better manned and better built.
The Portuguese naval infantry also had an advantage over the Egyptian Mamluks, not only because they were heavily armed and equipped (armor, arquebuses and a type of grenade made of clay with gunpowder inside), but also because they are seasoned professional seamen.
The tough state-of-the art multi-rigged Portuguese carracks and smaller fast caravels had been developed over the previous decades to cope with the storms of the Atlantic Ocean and are bristling with cannons.
The smaller Indian Ocean dhows and Mediterranean-type galleys launched by the coalition of the Samoothiri Raja, Gujarat and Egypt are no match.
The Portuguese ships are able to shoot their powerful cannons and thus dissuade the smaller craft from coming near them.
Even when they do come near, the smaller galleys and dhows are low in the water, and so unable to board the Portuguese ships, while being sprayed from above with small arms, grenades and smaller caliber cannon.
The battle endsin victory for the Portuguese, with terrible losses on the Gujarat-Mamluk-Kozhikode side, who had fought bravely but were at a loss as to how to counter a naval force, the like of which they had never seen before.
After the battle, Malik Ayyaz hands over the prisoners of Chaul, dressed and well fed.
To his surprise, Francisco de Almeida, who is ending his term as viceroy, refuses his offer to allow a Portuguese fortress be established in Diu, an offer that the Portuguese will soon seek ardently, and which he will manage to stall for as long as he was governor of Diu.
The spoils of the battle include three royal flags of the Mamlûk Sultan of Cairo that are sent to Portugal and are even today displayed in the Convento de Cristo, in the town of Tomar, spiritual home of the Knights Templar.
The Viceroy extracts a payment of three hundred thousand gold xerafins, but rejects the offer of the city of Diu, which he thinks would be expensive to maintain, although he leaves a garrison here.
The treatment of the Egyptian captives by the Portuguese is brutal.
The Viceroy orders most of them to be hanged, burned alive or torn to pieces by tying them to the mouths of the cannons, in retaliation for his son's death.
