Help me find information on Otto Von Bismarck's military exploits.

If anyone can that is... It would be greatly appreciated. :D

All I can find is information on his political agenda, and while that's nice and all, I was hoping to find information on his improvement of the economy of Germany and his military expansion such as that of the navy.

From well-documented sources, if possible... I was thinking of using Wikipedia... but... eh... <_<;
