Blood Angels vs Orks.
An invasion force of three Blood Angel's companies, deployed to the surface of Volistad in another attempt to capture and defeat the Ork command. The Orks fell back, leading the space marines into a trap. When the Blood Angels pursued the Orks closed the net around them and launched a massive assault which the Blood Angels barely managed to survive. This became a standard operational method for the Orks and it soon became apparent that these Orks were far more cunning that most. Repeated attempts to retake the space port failed leaving the Imperial forces high and dry.
