July 29 in Military History — On This Day

Battle of Stiklestad

Olaf II Haraldsson — who had forcibly Christianized Norway and alienated the powerful Norwegian chieftain class with his heavy-handed rule — was driven into exile in 1028 when Cnut of Denmark invaded and the Norwegian lords defected to him. Olaf returned from Russia in 1030 with a small force and was met at Stiklestad by a much larger army of Norwegian peasants and chieftains fighting for Cnut. He was killed in the battle. Within a year, Norwegian opinion had reversed: the Danish-backed regent was seen as oppressive, Olaf's relics were performing miracles, and the Archbishop of Nidaros declared him a saint. He was canonized as Saint Olaf within twelve months of his death — one of the fastest canonizations in medieval history.

Stiklestad is one of the most paradoxical battles in Scandinavian history: the king lost the battle and won everything that followed. Saint Olaf became the patron saint of Norway, and his cult was the foundation of Norwegian national and Christian identity for centuries. His death transformed Norse Christianity from a political imposition into a genuine national faith. The battle also marked the high point of Cnut's North Sea empire; within five years of Stiklestad, Cnut was dead and his empire dissolved.

Battle of Gravelines — Spanish Armada Routed

English fire ships scattered the anchored Spanish Armada fleet in the night, and English warships under Drake and Howard attacked the disordered fleet the following day off Gravelines, inflicting heavy damage. Storms later destroyed many fleeing Spanish ships.

The Armada's defeat preserved Protestant England and the Dutch Republic, ended Spanish hopes of invading England, and marked the beginning of English naval supremacy.
