Assassin's Creed 2 Walkthrough

Move to the first target and climb to the top of the building in the center of the restricted area. From the rooftop you can spot three guards outside the gate holding the prisoners. Assassinate two of 'em in one move and then kill off the other so that you can open the gate and free the prisoners. They'll follow you, but like Bartolomeo they have no idea how to climb.

Another map marker appears to the east, marking another group of soldiers to free. You can try to be stealthy or just charge in with your crew to wreck the place. Normally you need to be out of combat in order to open the gate holding in the prisoners, but if your crew is fighting the guards you should actually be able to unlock the gate. When the gate is unlocked, a quick cut scene interrupts the battle and essentially completes the fight for you. Score!

A third map marker leads you to the last batch of prisoners, and again you can just charge the gate, let your crew pick a fight, and then release the prisoners to end the mission without actually having to fight.

You're given command of a group of soldiers and tasked with bringing them to three different locations. Like Bartolomeo, they can't climb and they'll also pick fights with any guards with whom you cross paths. Watch your map as you run toward the target and do your best to avoid red dots that mark guards. When you reach the target, you'll find a few guards standing inside a small yard. Take 'em out, then step inside the yard to hit a glowing waypoint.

A second marker appears on your map when you've killed the first batch of guards. Again, make your way there while doing your best to avoid guards along the way—it's just easier that way. There are more guards at the map marker location, and another waypoint appears when you've cleared 'em out. A third marker leads you to the last group of enemy guards. When you've killed them, hit the waypoint for a final cut scene to close out the mission. Note, however, that on this final waypoint, the cut scene froze on us twice, leaving Ezio stuck in the gated yard. If this happens, just quit the memory and restart the mission.
