This fast and energetic track is an excellent opener for the album. It graphically depicts the violence and horror of a defence against a Viking invasion, starting with the sighting of the longboats and culminating in a last bloody stand against the invaders. An evolution from the early song 'Invasion' which appeared on The Soundhouse Tapes EP, 'Invaders''s driving power compensates for a somewhat weak chorus, and begins a tradition in battle songs that will later be followed and improved upon by 'The Trooper' and 'The Duellists'.
