When the cities of his County of Foix rebelled against the Royal tax collectors, because they raised the taxes to finance the expensive war against Flanders, Gaston supported his cities.
For this, the County was confiscated for a while by the Senechal of Carcassonne.
In 1308, he started a war against the Count of Armagnac, against the orders of the King, who had forbidden intra-French warfare.

In 1310, he inherited the Viscounty of Marsan from his aunt Constance of Moncada.
When another uncle, Ermengol X, Count of Urgell, died without a male heir, Gaston claimed the County of Urgell, but was no match against King Alfonso IV of Aragon, who incorporated Urgell into the Crown of Aragon.
On his return from yet another war against Flanders, Gaston fell ill and died in the Maubuisson Abbey, near Pontoise.
