From 1914 – 1918, humanity experienced the global conflict we now refer to as World War One. The rise of industrial capabilities and a wide range of technological advances, enabled "The Great War" to become one of the deadliest conflicts in history. WW1 has been described as the clash between 20th-century technology and 19th-century tactics. The significant advances in war machines on the sea, air and land created seemingly unstoppable weapons of mass destruction on every front. After suffering the horrifying effects of these newly devised technologies, both sides scrambled to provide a response. In some cases, new technologies were quickly developed, and in others new tactics were employed. This is a look at the rise of U-Boat technology and a resulting Q-Ship tactics used to counter their effectiveness.
