No this is not known as terrorism, its known as raiding. This practice was widespread and common in the Border Region of England and Scotland. The Border Reivers was a culture with established rules for their conduct. Night time raids would lead to revenge attacks to recover stolen property, and a clearly displayed revenge attack happened in broad daylight and anyone crossing its path, regardless of nationality, was required to join in and aid the attack. Terrorism is a specific issue, designed specifically to cause terror as its primary motive. A raid is to aquire something, generally land or something of value and occasionally future security. Calling 9/11 a dawn raid is about the same stretch of reality as calling a toothpick a spear.
