For more than 60 years, Colombia has been fighting against the oldest guerrilla group in the world: FARC. This time, we needed to create an action to invite them to demobilise and go back home. The problem is that every day they hide deeper in the jungle, so it's very difficult for us to make them catch our messages.

- We sent 6,823 messages and gifts inviting them to demobilise.- We got 1 demobilisation every 6 hours, between December and January.- In December 23th, we had one of the most historical demobilisations in the Colombian Pacific, in which an important leader demobilised with 9 more guerrillas and lot of military stuff.- This military stuff represents the 6% of all the military stuff in the history of the demobilisation program.- Demobilization levels of under 18s grew by 10%.- The President himself, and all the people from his government, joined the campaign, and also sent messages to the rivers.

We planned and executed a military operation. We made an official announcement through traditional media (such as TV, radio, press), inviting the guerrillas’ relatives and friends, people from war-affected towns, and people from all over the country, to send messages, letters and gifts, inviting guerrillas to leave their weapons, and come back home this Christmas.We put all this stuff in lit airtight capsules, illuminating the rivers nearest to their camps, and their way to the freedom.

We based our strategy upon 2 facts. We found out Christmas is the most emotional and hard time for guerrillas, because it's when they feel further from their families and their loved ones.As guerrillas don't use any of the traditional media because of their war condition, the rivers from all over the country have become their most important channels of communication and transportation. Every FARC base camp is built close to a river in the country. The rivers go to the most intimate point of the illegal armed forces, more than any other media.
