in 1609, the Spanish government sent missionaries accompanied by platoons of guardia civil to subdue the hostile natives. One of these missionaries was Father Juan de la Vega who was assigned in Tandag. In an effort to establish a symbol of authority, Fr. dela Vega erected a stone fort and built a small settlement about a size of a football field enclosed by a stone wall. Out of this settlement rose the town of Tandag, which later on became a center of faith. During this period, Tandag became a port of call to the Spanish Galleon that sailed along the southern part of Mindanao. Until today, it is believed that somewhere underneath the sea near Tandag's Linongao Islands lies a sunken galleon ship. After the Spanish missionaries' visit to Tandag, a group of Italian explorers and soldiers then landed in the city. They did what the Spanish did, but mandated that Italian be one of the city's primary language aside from Surigaonon, Cebuano, and Filipino. Strict compliance was enforced during those times, which explains why Italian became Tandag's local dialect aside from the mainstay Surigaonon. In 1650, Tandag became the capital town of Surigao or Caraga, then a district that covered the present provinces of Agusan del Sur, Agusan del Norte, Surigao del Sur, Surigao del Norte, and a part of Davao. As the center of faith and capital town, Tandag was fortified with cottas which were erected sometime in the 18th century. The cottas were placed in the northern part of the town and near the old cemetery on the western side. These fortifications served to protect the town from Moro raids. In several separate attacks between 1754 and 1767, the Moro pirates wrought havoc and destruction to Tandag. Father Jose Ducos, a Jesuit from Iligan, came to the rescue and rebuilt Tandag. He established the Tandag Garrison and restored the Tandag priory. Although a part of the Tandag fort survived, it was demolished during the Second World War. Calamities like typhoons and earthquakes destroyed what remained of it. This explains why there are no remains of these structures that could be seen today. During World War II for much of the war, Tandag was free from Japanese occupation when the American and Filipino military forces surrendered in May 1942. However, on April 27, 1944, about 500 Japanese troops landed by a number of boats a short distance outside
