large naus of the 4th Armada. The Trimumpara Raja of Cochin urges Gama to avoid the fleet and just set sail for Portugal at once. But Vasco da Gama refuses to revise his plans. He needs to return to Cannanore to deposit the factor Barbosa there and pick up a cargo of ginger he had ordered. And he was itching for revenge for the ambush. Early February, 1503, After a final audience with Raja Trimumpara, taking aboard his ambassador to the Lisbon court, leaving Diogo Fernandes Correia as factor in Cochin, and taking Cabral's old factor Gonçalo Gil Barbosa, to serve as factor in Cannanore, Gama's fleet (around ten fully laden ships) finally leaves Cochin. They are soon joined by Sodré's caravel squadron, and set sail warily towards Cannanore, guns ready for the Calicut ambush. Gama and Sodré spot the Calicut fleet of Coja Casem and Arab privateer Cojambar, near the coast, out of Calicut harbor. In one of the first recorded instances of a naval line of battle, Gama's spice naus and escort caravels sail in a line end-to-end, concentrating all their immense firepower as they pass against the twenty large Arab ships of Cojambar, before they can get organized, sinking a number of them and doing immense damage to the remainder. Although the Arab squadron is out of commission too soon, Coja Casem nonetheless proceeds forward with his fleet of Malabari sambuks, hoping to use their speed to outmaneuver the guns of the heavy-laden naus and reach for the grapple. But Gama sends the escort caravels under Vicente Sodré to intercept them in their tracks, while the cargo naus hurry on toward Cannanore. Although the caravels are outnumbered, it is not much of a battle. The fight is essentially over when Pero Rafael and Gil Matoso quickly board and capture Coja Casem's flagship (oddly, found with a lot of women and children on board). The Calicut fleet breaks up and rushes back to port. The pursuing caravels capture a number of sambuks, which they proceed to tow and set on fire before Calicut. The long-prepared ambush has been foiled. Danger dispelled, the caravels proceed to Cannanore to make junction with the main fleet. The Battle of Calicut, like the previous year's naval battle of Cannanore, once again demonstrated the critical importance of the technical superiority of Portuguese ships and naval artillery. But it also demonstrated to the Portuguese
