Poor OP and its two settlers! The actuall business of getting rid of the barbs can be left to the military advisor to decide. Obviously the new priority should be to build at least two new settlers. One to refound OP in the honour of all those lost citizens, however we could build it one square to the SW (On the irrigation) so that we could build Gary's filler. We also need at least two settlers for the East Island and another for the filler NE, NE , NE of MD. Also some more defensive units are probably needed to prevent lightning from striking twice.
