Two Birds, One Blade

"Two Birds, One Blade" is a memory in Assassin's Creed II.

Description
This memory involves the assassination of Silvio Barbarigo and Dante Moro. Ezio climbs to the top of the highest point in the Castello, and activates a flare gun-like mechanism, thus signaling the Mercenaries to begin attacking Silvio's men. He then goes to help Bartolomeo d'Alviano, and he fights Dante. After some time, Dante and Silvio begin to flee to the ships but are assassinated by Ezio before they can escape.

Outcome
Silvio Barbarigo and Dante Moro are killed. The Castello is freed from Templar power.

Trivia

 * Even if Ezio assassinates Silvio and Dante at different times, they will both appear in the same Memory Corridor.
 * If after assassinating Silvio and Dante, you hide in a nearby well, the final cutscene will play without Ezio being in it, although his voice will still be heard.
