My first ever ambush consisted of 2 sqauds. 1 had axes, the other whips. The migrant wave before the ambush, I had drafted 10 imigrants out of my total 30 dwarves (all the immigrants) and had them spar to become legendary wresters. Then, I armed then with masterpiece, or the quality below it- obsidian swords, decent bone armor, and wood shields, and had them spar more. They were at all at the "swordsdwarf rank" when I got the ambush message.
The goblins pushed by fisher into a pool of water he was fishing at. Then, they attacked my woodcutter, who managed to kill 3 and cut the legs off of 2 of the mace goblins.
I quickly mobilized my military and drew up the bridge; as this was my first combat I just thought "hey, set the actions all at once!". Only 1 dwarf from the military crossed the bridge before it was pulled up, and 3 fell into the moat. It was connected to a brook, so they all made it out alive but behind the wall.
I check in, and see my 1 dwarf charge the mace squad to save the woodcutter. By this time, the woodcutter has lost BOTH legs, but he was Superdwarvenly Tough, so he was passed out and not dead. I should note that he and the fisher were both drafed so I could have them run away from the ambush, but it didn't help. So, my legendary wrestler/ swordsdwarf with a masterpiece obsidian swords runs in. He massacres the sqaud without so much as a scratch, and when there was only 1 macegoblin left the whip squad charges in. They proceed to circle my dwarf, but he still beats the shit out of them. He started the battle with the second squad in a "tired" state. He kills all of the whip goblins incuring some moderate damage to his upper body, but he passed out due to extreme pain. I thought they were all dead, I was wrong.
I check the fisher, and it seems that 1 goblin fell into the pool with him, and he killed it somehow. My legendary fisher killed a legendary whip goblin. It must have been stunned in the water, but the entire murky pool was filled with blood. I look up, and notice that same legendary macegoblin that was rescued by the whip sqaurd, limping toward my passed out swordsdwarf; leaving a trail of blood behind it. Then, my drafter fisher runs in; wrestled with it and makes it overexert itself and they both pass out.
My woodcutter was rescued, and so was the fisher and militrary dwarf. All were rewarded with platinum plated engraved rooms to recover in. The woodcutter never woke up, he slept for 5+ years with no sign of recovering. The fisher recoved from his loped off arm and mangled other arm, but was ambushed and killed the next ambush. After that, all the seigers were SLAUGHTERED by the 10 dwarfs; even up to 6 squads could be dispatched by 3 well trained, well armed, moderately armored legendary swordsmen/wrestlers
