The goblins then realise that the dwarves will not stand let the fort be taken so lightly. So Blayser is sent to re-force the siege there.
Gimli, along with the other two dwarf captains, launches an all out attack on the fort.
So Gimli is going all out to secure the fort, as the goblins must rush to claim it's walls before the dwarves do or surely they will dominate this field and all the others....
