A perfect mission

10 minutes later, 150 kilometres from the Redliner tribe's main base, 17 newly spawned Blackthorn zerglings and 2 mutalisks clashed with the Redliner forces; extinguishing them, with at least half of them becoming casualties. As they advanced to 80 kilometres away from the Redliner tribe's main base, they were then wiped out by the newly spawned units of the Redliner tribe.

This to-and-fro tussle persisted; naturally, with every new wave of Blackthorn units, the gap towards the Redliner main base would decrease a little! When the Overlord they were riding in swept past the battle line, the newly spawned forces of the Blackthorn tribe had managed to gain within 20 kilometres from the Redliner tribe's main base.
