Yes, for a time. the Muslims got it back after a while, though.
the battle of Dorleaum in modern Turkey, the conquest of Antioch
and the conquest of Jerusalem can be given as examples of Crusader
victories. all these advancements took place between 1096 and 1100
Also, in the 1190s, Richard the Lionhearted pretty much helped save
the crusader states and let them live on for another hundred years.
Just as when defeat seemed certain for crusaders with only one
settlement left in the Holy Land, Richard arrived and recaptured
the entire coastline from Saladin, the Muslim leader. If I remember
correctly, Richard did not even lose a battle to Saladin. But in
the end, strategic impairments, such as fear of overstretching
supply lines, prevented him from attacking Jerusalem.
