Haytham Kenway's Early Death
After the last scene in the memory, you have to save Haytham, resulting in a fight. Here's a way to avoid being detected. You'll need to have purchased the gun that shoots three bullets at once. With it you can take out all three of the men holding Haytham captive at once, avoiding detection.

After that the other soldier targets appear, but since you are anonymous they won't attack on sight. Kill four of them, using poison to avoid detection. Make sure you called a horse to replenish the poison (crafted saddle bags required).

After the four other guards die, Haytham will run away. Put him between you and one of the guards. As long as the guard can be targeted, you can throw the poison. Guess what? Haytham is affected by the poison! Of course you shouldn't use the poison too early, or you will desynch shortly afterward. Wait for the four guards to die first. A good time is when Haytham starts talking. Shortly afterwards the game doesn't record his health and he runs away.

Haytham Kenway's Disappearing Act
I was curious as to where Haytham runs away to, so I followed him. The game developers tried to make it impossible to follow him by placing a distance restriction from the targets, but as it turns out, there is no distance restriction if you aren't detected.

Haytham runs a predetermined route for a short while, then vanishes in thin air. It seems this is based on a certain time limit, not on him reaching a certain area. Even if you killed him with poison or stopped him from running he will still disappear. There was even one time when he was fighting the other soldiers while Connor was still anonymous. After he started talking he continued fighting the soldiers instead of running away. After a short while he disappeared, and the soldiers walked away (because they were so used to things like this happening).
