Apollo missions to the Moon used the following manuevers: 1. Launch into an Earth parking orbit. 2. Trans Lunar Injection to send the vehicle toward the Moon. 3. One or more mid-course corrections on the way to the Moon. 4. Lunar Orbit Insertion maneuver to place the spacecraft in lunar orbit. 5. Descent Orbit Insertion to lower the Command and Service Modules/Lunar Module to a lower orbit. I believe that this was only done on Apollos 15, 16, and 17. 6. Powered Descent Initiation: Firing of LM engine to land LM on the Moon. 7. LM Ascent: Takeoff from lunar surface and placement into lunar orbit. 8. Trans Earth Insertion: Firing of SPS engine to leave lunar orbit and return to Earth. 9. One or more mid-course corrections on the way home. The magnitude of the various maneuvers varied from mission to mission. The best source of info are the mission reports prepared by the Mission Analysis and Planning Division at Johnson Space Center. They're probably in the JSC technical library.
