Unfortunately died and took only one stand by him.
In second battle I used it as splitter of brigade. He charged flame cannon and destroy him. But I forgot that engaged units (troops were by side of cannon) are by corners too. So he lost fight by supporting units. After that he retreated and both of troop units pursued him and cought him by sides. Giant was killed by smash of attacks.
But after that !!! both units reformed and touched by sides, so they create a new brigade. What a disappointment for me any my dead Giant.
Experience: Giant shouldn't charge alone. And if he charges, he must charge only against stand of troops.
