Star Wars (Legends): Republic, book 55: The Rainmakers
W. Haden Blackman et Brian Ching2003

General Kenobi and his First Lieutenant, Anakin Skywalker, find themselves transferred to a post on the rain-soaked planet Jabiim. The fighting is fierce, and the vast majority of the locals have sided with the Separatists, leaving the Republic's outposts isolated and vulnerable. In the face of mounting casualties and shrinking resources, Obi-Wan leads what he hopes will be a crippling attack on the enemy. But the environment is against the Jedi and his clone troops; the rain won't let up, their war machines bog down in the mud, and air support is non-existent! This might be Obi-Wan's final mission!
