After Lecomte's premature death in 1695, Martin began to collaborate with Pierre-Denis Martin who (depending on the source consulted) may have been his cousin, nephew or brother. In 1699, they completed a new series of works lauding the achievements of the King, which was installed at the Château de Marly. At this point, he became the official painter for the King's campaigns against the Protestants in Dauphiné, the Siege of Mons and the Siege of Namur.
