Battle in Balin's tomb

Previously in the Mines of Moria booklet:

Legolas gets struck down by goblin arrows 

Aragorn succumbs to Goblin numbers

Merry secures a trapdoor while the others hold the goblins

Legolas closing the final trapdoor

The score is 2-1 in favour of the goblins going into Balin's Tomb the final scenario in the mines of Moria booklet.
Strangely they didn't include any about the bridge of Khazad-dum or the flight over the stairs.

Scenario 4: Battle in Balin's tomb
The Fellowship find a stone chamber where Gimli's cousin Balin was laid to rest after meeting his tragic fate. Their grief is interrupted by the booming of drums and the the arrival of yet more goblins, this time "They have a cave troll".

Objectives: Good must kill the cave troll. Evil must kill four members of the Fellowship before the cave troll is killed.

Special rules:
Trapdoor - At the end phase roll a D6, on a 4,5 or 6 a goblin with either spear, bow or shield may be placed in contact with the trapdoor.
Cave troll - At the end of a turn where both sides have drawn the priority roll-off the cave troll may be placed in base contact with the doorway. If models are blocking the trolls entry then they must be moved out of the way, unless they are newly arriving models, then the troll arrives in the next turn.
The doorway - At the end phase roll a D6, the result is the number of goblins with either spear, bow or shield may be placed in contact with the doorway, if there is not room to place newly arriving models then the models blocking their entry may be moved aside. Unlike trapdoors the doorway may not be sealed.

Goblin forces: 24 goblins (8x spears, 8x shields, 8x bows) , Cave troll

Playing board: 56cm x 42cm

Giving the Fellowship their second victory and the overall score to 2-2.

The Fellowship managed to close a trapdoor, reduce the effectiveness of the second and kill the troll. Things got sticky as the troll entered on the third turn, and after Sam and Pippin fell being used to reduce the number of enemies facing Boromir and Aragorn. However when Legolas and Gimli came to help the hobbits use had been fulfilled. 

The Performance of the battle award has to got to Boromir, as he won all of his combats and killed 6 of the 10 goblins coming through the doorway. Aragorn did well to kill three and get two wounds on the troll but lost a couple of combats meaning he allowed more goblins to be in the tomb.

Flop of the battle goes to the troll, that couldn't inflict wounds on Aragorn despite being surrounded, and Gimli in a face-off.

The Fellowship easily handled the goblins at the trapdoors, since I used the movement as depicted in the booklet. 

Aragorn and Boromir move to the door, Gandalf and the hobbits to one trapdoor, Legolas and Gimli to the other.

Gandalf's sub-force outnumbers the goblins initially meaning they had to get quick kills while the number ratio was in their favour and they are unlikely to have strikes against them, easier when they were in attacking range from the first turn.

Gimli and Legolas have to charge full speed towards the second trapdoor, no shooting from Legolas, before one or two goblins come through the trapdoor when they get there, so less turns are spent killing them when even more goblins can come through.

Lastly Aragorn and Boromir are best suited to defending the doorway, as they have the most combined attacks and wounds and need to kill three or four goblins per turn, so they won't get surrounded. Also as they are better candidates for killing the troll when it arrives.

Generally once the trapdoors are sealed Gimli, Legolas, Boromir and Aragorn can easily stem the tide of goblins coming through the door and kill the troll.

Until then
