For a good five minutes the first and the second legions had the absolute upper hand in battle as the Crimson shadow soldiers that had attacked them from the flanks could not handle the fully prepared and shielded Bloodfall soldiers.
As Assassin's their speciality was in taking their enemy by surprise.
Even within large battlefields their preffered method of attack was to lurk through the blindspots and take advantage of ensuing battle between two people to kill the opponent unaware.
But their choice of weapon in daggers, short swords and knives proved to be ineffective when facing shields, longswords and spears against men who saw them coming clearly and were prepared for fight.
Although faster, the crimson shadow soldiers found it difficult to create an opening against the on-guard Bloodfall soldiers who through sheer numbers outnumbered them and killed them at the slightest opening.
