If you fail an attack on another player you are asked if you want to call for assistance. Doing so (at a small fee) sends a notice to all of your allies with a link to the player you failed to attack.

If the follow the link and attack said player, it is called an assisted battle. They get Dorri and Battle Points, but you get the treasure you originally targeted.

This has apparantly happened to you. Someone failed an attack on you and called their allies for help.
