Therefore, from the fort, it was easy to control the ships and boats passing to Kodungallur through this river.

The fort was constructed under the supervision of Pedro Álvares Cabral[7] and was under the command of Urbano Fialho Ferreira after the completion.

After the Dutch army captured important parts of the fort, the Portuguese boarded boats and escaped to the Ambazhakkad seminary.

The agreement was executed between Raja Kesava Das, the Diwan of Travancore and John Gerard Van Angelbeck, the Dutch governor.

The construction of Nedunkotta or the Travancore Lines is considered to be a unique and unparallel episode in Indian History by historians.

[11] The Maharaja requested the Madras governor (Mr. Holland) to issue orders to the British contingent to co-operate with him in case of an attack from Tippu Sultan which was expected every moment.

Mark Wilks records that the Sultan was directly involved in the attack, that he suffered a leg injury and was crippled for life, and that his valuable jewelry was confiscated.

[13] However, based on the Mathilakam documents, A. P. Ibrahim Kunju evaluates that the Sultan was not directly involved.

[14] The Madras governor, Mr. Holland, refused to help Travancore, because he thought that the Maharaja had acted unlawfully in purchasing the Dutch forts [15][16][17] Unable to influence the King of Travancore in any way, from 12 April 1790, the Mysore army again attacked Nedumkotta.
