Drain the Oceans is grossly inaccurate as an historic programme which should be educational for the viewer. In the opening shot of the UK map for the Jutland episode depicts that in 1916 Scotland, England & Wales as british but not Ireland! At that time Ireland, the whole of it, was British. It was not until 1922 that Ireland became an independant country. Even then the Northern six counties remained british and still are.
