The best place to pull this off (if you don't mind killing Ottoman guards) is in Sequence 4, the memory where you retrieve Sofia's parcel from the ship. There are enough guards around the port to string together 2 streak (3 if you're lucky), but you have to lure them together. Then just roam around before completing the memory at Sofia's shop and get other groups of guards together, lather-rinse-repeat. Janissaries are not out on patrols at this point in the game, so all the guards will go down with one hit in a kill chain.
That's how I completed the challenge, anyway. On my next playthrough, I'm going to try it with Byzantines during "capture the tower." The only way I've noticed replaying memories to complete challenges doesn't work is replaying memories in Cappadocia. For some reason, they don't seem to count there.
I tried that, it didn't count </div></BLOCKQUOTE>Originally posted by BradKinn:

Load a memory from an earlier sequence and free roam instead of starting it.

That's strange. It should.
