However, after several amazing victories in 1914 (Pathfinder, Aboukir, Cressy, Hogue, & Hawke sinkings) they gradually realized that taking the battle to the enemy was a feasible strategy - especially through an anti-commerce campaign in distant waters.

The Germans had several important advantages over other submarine fleets:

-Reliable diesel propulsion. MAN & Germaniawerft diesel engines were quite good, and improved during the war. Other navies like the French wasted time with petrol boats and struggled to build good diesels.

-Good weapons. The G6 and G7 torpedoes and mines used by K.M. submarines were excellent - in fact, German WWII torpedoes were close relatives of the WWI G7. British torpedoes, on the other hand, often ran deep or failed to explode.

-Aggressive officers. Germany doesn't seem to have had a problem with overly-cautious or timid commanders like other navies. U-Boat Kaleuns showed great tenacity in the field; the records of Hersing, Rose, de la Periere, and others with over 100,000 tons sunk speak for themselves.

Interesting. Obviously, you have done your research. Curious, because I seem to find contradictory information in various sources. Did Allies have active sonar, i.e. ASDIC during WW I? I know they had hydrophones (referred to as sonar sometimes). Did they sink any u boats via depth charge attack ? After sonar detection?
