The action at Lanark was an attack at Lanark, Scotland during the First War of Scottish Independence in May 1297. The Scotsman William Wallace led an uprising against the English and killed the Sheriff of Lanark, William Heselrig. The attack was not an isolated incident, but rather saw Wallace joining in with uprisings taking place across Scotland. Not much is definitely known about this incident. The best account comes from the Scalacronica by Thomas Grey, whose father, also called Thomas Grey, was present. A fracas broke out at a court being held by Heselrig, but Wallace was able to escape with help from an individual named Innes who may have been his wife. He then came back with some supporters and attacked Heselrig and his men, killed Heselrig, nearly killed Thomas Grey, Sr. and set fire to some houses.
