This AI attempt to tell the story of HMS Ganges falls short in several ways as you will see if you study the history of HMS Ganges. A couple of items to note - The trainees were known as Boys and later as Juniors but never Cadets. Cadets were trainee officers and were trained at Britannia at Dartmouth.
It doesn't mention the fact that training was first carried out on an a ship and then moved ashore at Shotley.
