Not now, but in the 1400s.It's a bit early for gunpowder weapons to be of much use,especially in the 1300s.It's only useful for sieges but beyond that,don't bring it to a field battle.
These are still useful and the artillery will still help in fortifying lands.I don't think that the first practical firearms (Arquebuses) were introduced till sometime in the 16th century. Aside from seige-cannons the other thing that might be around are "Bombards" (The very first mortars basically).
Could you explain this in more depth?If there is no war of two Peters then from what I recalled England shouldn't lose it's conquered territories in Aquitaine that was gained following the Treaty of Bretigney due to taxation in that area to fund English intervention.
