, France, he entered the Knights Templar well before 1260, because on that date he was taken prisoner during an attack on Tiberias. His great piety was deemed worthy of the nickname of "Gaudin Monk".

In 1279, Sir Thibaud fulfilled the function of "Commander of the Land of Jerusalem" (unconfirmed), the fourth most important function in the Templar hierarchy. In 1291, he rode at the side of Guillaume de Beaujeu

. The remaining knights of the order, men, women and children found shelter in the Temple, the great fort of the Templars. Pierre de Sevry, Marshal of the Order, Thibaud Gaudin, treasurer of the order, and their knights were the last to defend Acre. After trying to break in for a whole week without success, Al-Ashraf Khalil offered the marshal of the order to embark for Cyprus with all their possessions. Pierre de Sevry agreed. An Emir and 100 mameluks were permitted to enter the fort, but they began to molest some women and boys. Furious at this act, the knights slaughtered the mameluks and barricaded themselves again. That night Pierre sent the treasure of the order with its commander, Thibaud Gaudin and some non-combatants, by boat to Sidon. Acre fell the following day.

Thibaud Gaudin arrived with some knights at Sidon, where he was elected Grand Master. The Templars were determined to stand, but because they lacked numbers to properly defend the large city, they evacuated the city and moved to the castle of the sea. Thibaud Gaudin went to Cyprus in the hope of gathering reinforcements. To many, this was regarded as an act of cowardice. The Templars fought bravely, but once the engineers started building a causeway, they sailed away to Tortosa. July 14, 1291 emir Al-Shujâi entered the castle and ordered its destruction. The reinforcements never came. Beirut was taken on July 21, the castle of Ibelins and its walls completely destroyed. The sultan occupied Haifa on July 30, and the monasteries of Carmel destroyed. In early August, the Franks held nothing more than two fortified towns, both occupied by Templars. However, the garrisons were too weak to face a siege, so Tortosa was evacuated on August 3 and Athlit on August 14. They left for the sea fort of Ruad, two miles off the coast of Tortosa, which would remain in their hands until 1303, when the future of the order was in jeopardy.

In October 1291, a general chapter of the order met in Cyprus

. This meeting confirmed the election of Thibaud Gaudin as Grand Master and named new dignitaries in the important positions within the hierarchy of the order. On that occasion, Jacques de Molay was named Marshal, to succeed Pierre de Sevry, who died at Acre. Thibaud Gaudin tried to reorganize all the Templars after the devastation of the recent battles. Moreover, it was necessary for him to defend the Kingdom of Armenia from the encircled Turkish Seldjoukides and the island of Cyprus, occupied by a multitude of refugees. Apparently the task proved daunting for Thibaud Gaudin; he died in 1292, leaving an enormous rebuilding task for his successor.
