Theconquest of Santarém took place on 15 March 1147, when the troops of theKingdom of Portugal under the leadership ofAfonso I of Portugal captured theTaifa of Badajoz city ofSantarém (at the time called Shantarin).
On 10 March 1147, King Afonso I of Portugal departed fromCoimbra with 250 of his bestknights[2] intending to capture the Moorish city of Santarém, a goal that he had previously failed to achieve.[2] The conquest of Santarém was of vital importance to Afonso's strategy; its possession would mean the end of the frequent Moorish attacks onLeiria and would also allow a future attack onLisbon.[3]
The plan now was to attack the city during the night under cover of darkness, in order to catch the Moorish garrison by surprise.[2] King Afonso had previously sent the PortugueseMem Ramires to Santarém disguised as a businessman, in order to secretly study the city for the conquest.[2]
After the first day of the journey from Coimbra to Santarém, King Afonso I sent an emissary to Santarém announcing to the Moors that thetruce had ended, for which three days' notice was required.[1]
On the night of 14 March, King Afonso and his army arrived at Santarém[2] and hid ladders in the fields.[1] Before dawn the next morning, 25 knights scaled the walls, killed the Moorish sentries and forced their way to the gate, allowing the main Portuguese army to enter the city.[2] Awakened by the screams of their sentries, the Moors ran from all sides to face the Portuguese attackers in the streets, offering very strong resistance, but ended up being defeated and slaughtered.[2]
By morning the conquest was already complete and Santarém became part of the recently formed Kingdom of Portugal.[2]
One of the attacking knights was Mem Moniz de Gandarei (grandfather of Portuguese politicianMartim Machado Pires), who was said to have broken down the city doors with an axe.[4]
After the conquest of Santarém,Afonso I of Portugal turned his attention to the important Moorish city ofLisbon, which he wouldconquer in October with the help of a crusader fleet of theSecond Crusade who stopped in Portugal while on course to theHoly Land.[5]
The earliest and most detailed source for the conquest of Santarém is theDe expugnatione Scalabis.[6]
