British developed the first armored tank
In the 1st battle these were used in, 18 out of 48
got stuck in the mud

of May 7th, as the ship approached the British Isles, a
crew member spotted ominous air bubbles and
streaks in the water below. The ship had been
attacked by German torpedos. 18 minutes later, the
