I realised while reading about French Naval expansion up to WW1 that I had no idea what the French Navy actually did in the war. I've always got the impression the British Navy fought and kept the Germans bottled up in the North Sea. Wikipedia says the French faced the Austrian in the Mediterranean, which doesn't seem like the most challenging task, and had an important role in the Dardanelles campaign.
Can anyone expand on what the French Navy did in the war? Is their apparent lack of action simply because with the Germans kept in check by the Royal Navy there weren't any big set-piece naval battles? (Thinking about it, I can only name a single naval battle from WW1.)
The French Navy helped to maintain the Otranto Barrage, a blockade of the Adriatic Sea that kept the Austro-Hungarian Navy bottled up. They participated in the Dardanelles Campaign, and as /u/fcewen00 mentioned, they engaged in a number of clashes in the Mediterranean. As per the Anglo-French Entente Cordiale, the British watched over the Channel, while the bulk of the French Navy operated in the Mediterranean with British support.
