In the late autumn of 1335, Strathbogie, dispossessed Earl of Atholl, and Edward III set out to destroy Scottish resistance by dispossessing and killing the Scottish freeholders. Following this, Strathbogie moved to lay siege to Kildrummy Castle, held by Lady Christian Bruce, sister of the late King Robert and wife of the Guardian, Andrew de Moray. Her husband moved his small army quickly to her relief although outnumbered by some five to one. However, many of Strathbogie's men had been impressed and had no loyalty to the English or the usurper, Balliol. Pinned by a flank attack while making a downhill charge, Strathbogie's army broke and Strathbogie refused to surrender and was killed. The Battle of Culblean was the effective end of Balliol's attempt to overthrow the King of Scots.
