The Cophen campaign (Ancient Greek: Κωφήν, romanized: Kōphḗn) was conducted by Alexander the Great between May 327 BC and March 326 BC against the Aspasioi, the Guraeans, and the Assakenoi tribes in the Kabul, Kunar, Panjkora and Swat valleys, in present-day Afghanistan and Pakistan. The main aim of Alexander was to secure the Macedonian line of communications so that the Macedonian army could proceed into India properly.
