The Jeune Ecole was the preferred French naval doctrine in the late 19th century as a way for France to potentially counter- the strength of the British Royal Navy at the time. In a nutshell, the idea was that flotilla's of smaller, powerfully armed ships could attack and counter the big battleship fleets popular at the time.

The time period of the late 19th to the early 20th century saw great changes in the abilities and power of naval weapons, armor, and propulsion. It was a time of great confusion and uncertainty on how military power could be used to project power. At the time, no one was really sure what the way forward would be. Into this space came two competing schools of naval doctrines that a nation could follow.
In Hindsight, we can see that Mahan's Seapower theory gained dominance and was the preferred doctrine of major (and wanna-be major powers), but the Jeune Ecole was there as an alternative.
1. Can you envision a scenario where the Jeune Ecole school would/could of become dominant?
2. What in your mind would a hypothetical engagement between the two schools look like?
3. What technology leaps would have been necessary in the early 19th century to make Jeune Ecole the dominant doctrine?
