The siege of Cannanore was a four-month siege, from 27 April 1507 to 27 August 1507, when troops of the local ruler (the Kōlattiri Raja of Cannanore), supported by the Zamorin of Calicut and Arabs, besieged the Portuguese garrison at St. Angelo Fort in Cannanore, in what is now the Indian state of Kerala. It followed the Battle of Cannanore, in which the fleet of the Zamorin was defeated by the Portuguese.[3]
The old Kolathiri Raja who had energetically pursued the Portuguese alliance died sometime in 1506. As the succession was disputed, the Zamorin of Calicut, as formal suzerain of the Kerala coast, nominated an arbitrator to sort through the candidates. The new Kolathiri Raja of Cannanore was consequently indebted to the Zamorin and less inclined to the Portuguese.[5]
Hostilities were in large part due to the Portuguese sinking an Indian ship and killing the crew by stitching them into sails and throwing them into the sea, on the grounds that they were not carrying one of the Cartaz, the passes the Portuguese were imposing on all ships of the region.[6] Such passes had to be signed by either the commander of Cochin or Cannanore.[7] The population of the adjoining state of Kōlattunād was greatly angered by this event, and asked their ruler, the Kōlattiri, to attack the Portuguese.[7]
Siege
The siege started on 27 April 1507, and was to last for four months.[7]
The Kōlattiri had 40,000 Nāyars attack the position.[7] The Zamorin supplied the ruler of Cannanore with 21 pieces of artillery and 20,000 auxiliaries.[7][8]
The firepower of the garrison under Lourenço de Brito allowed it to repulse massive attacks involving thousands of men.[7] The siege soon entered a stalemate, with the Malabari trenches being protected from Portuguese cannon fire by walls of cotton bales, and the Portuguese being slowly forced into starvation.[7]Castanheda's detailed report of the siege states that they were then surprised – and saved – by a tidal wave of lobsters that washed ashore on 15 August.[9] A major assault before the Onam festival nearly overcame the defenders, but was eventually repulsed. However, a large part of the garrison was wounded in the attempt.[7]
The Portuguese garrison was on the verge of being overwhelmed when, on 27 August 1507, a fleet of 11 8th Armada ships under Tristão da Cunha arrived from Socotra. The fleet landed 300 Portuguese soldiers, forcing the lifting of the siege and relieving the fortress.[7][8]
Peace was negotiated between the Portuguese and the Kōlattiri Raja, confirming the continued presence of the Portuguese in Cannanore and the resumption of their access to its spice markets.[7] These events would eventually be followed by the defeat of the Portuguese at the Battle of Chaul in 1508.
^Logan (p.314) identifies the offending captain as "Gonçalo Vaz" and suggests he was acting on his own. Cannnanore fort captain Lourenço de Brito protested his innocence, asserting he authorized no such action. Gonçalo Vaz was immediately dismissed by vice-roy Francisco de Almeida, but this did little to assuage the angered people of Cannanore.
