I don't get it Guys...
I am up to my third year and only dogs have died...
I control the only way into the Fortress...
I overwatch EVERYTHING, Meaning that if the woodcutter is cutting wood, then everyone is hauling that wood back in, at most there is three outside at a time, the one that cuts the wood, the one that hauls the first lump wood, and the next one coming out for the one that was just cut down...
I made sure of my Project was allowed by Sol before starting it, it was...
And now I have 6 Champion Wrestlers/Training Marksmen that are stocked up with Steel and Iron Bolts I traded from the Human and Dwarf Caravans to watch over them for Harpies...
I don't make enemies with Elf or Human and I watch every spawn of Beak/Harp on the over map, (Hostiles are the Redshaded Squares)...
The greatest thing is I have a lot of luck it seems, the only time I have rolled back to the beginning of the year was when I lose all my Miners to Cave ins/Magma Problems. (Even then they are rare). Cause that normally means I lose the Picks too. If someone is caught by Harpies, they outrun them with a lot of luck too, I have had Harpies chase down three different dudes and they all got away, Once towards the axe of My Woodcutter/Champs, sometimes just clean get away. At the start I made sure everyone was away from the Pipe by setting up a meeting area where I was diggingin, and constructed a roofed (via Ramp outside) construct around my Stairs so that only way in was through the doors and past the dogs, this was before digging out the only path for Merchants to use, then it was even easier cause then they could only enter the Fort from that way...
Heck even only one dog has died, and that was to distract the first Gobbo Ambush...
