Naval Battle of the Tejo
The Battle of Tejo took place in July 1384, in the Tagus river (Tejo in Portuguese), between a Portuguese naval force of 34 ships (5 of which were major vessels) with the objective of supplying the besieged city of Lisbon with much needed supplies and the Castilian fleet led by Sanchez de Tovar. Although the Portuguese lost three ships (Castilian casualties are unknown), Portuguese success in reaching Lisbon and breaking the blockade with much needed supplies was a major victory for Portugal. The Castilians would later retreat from the siege. See also
