I am looking for a book I read on kindle a number of years ago (not an account I have access to now).
The concept was that 2 midshipmen (I think that was their rank) are transported forwards in time from a battle which took place in the Napoleonic wars on a Royal Navy warship to a Royal Navy spaceship.
Part of the story I recall being about their acclimatisation to the future and their training for the navy of this futuristic world.
Could this be the Harry Heron series by Patrick G. Cox? The cover blurb for the second book in the series, Into the Unknown, reads:
Harry Heron: Into the Unknown continues the exciting story begun in Harry Heron: Midshipman's Journey, the flagship book in the series. A freak accident on board the HMS Spartan during a sea battle with the French navy in 1804 catapults Midshipman Harry Heron and his shipmates Ferghal O’Connor and Danny Gunn four hundred years into the future, landing them on the NECS Vanguard, flagship of the World Treaty Organisation Fleet. While Captain Blackwood and Major Heron sort out the mystery and determine whether the young men are alive or dead, Harry and his friends are faced with the challenge of learning new roles aboard a spaceship. Just as they have found their footing, they are called upon to assist the Fleet in a rescue mission on the planet Pangaea, giving them the opportunity to prove that their unique skills from the past are still very relevant in the far distant future.
