Why the torpedo-battleship concept did not take hold

What was the torpedo-battleship concept before the First World War?

Navies explored it, but gun range greatly exceeded torpedo range, making the concept impractical for capital-ship combat.

Several navies considered the torpedo-battleship idea, and Beatty became especially associated with it after the First World War. The concept seemed to offer answers to several capital-ship problems. Its central weakness was tactical range: torpedoes could not reach targets at the distances where a battleship's main battery could fight. That mismatch prevented the idea from delivering what its advocates expected.
