When I did my establishment reseach in the National Archives, I also transcribed the Record of Unit Dispositions. I started from January 1803 and this shows 19 LD in India at that date. They moved from India to Great Britain in April 1807, then Great Britain to Ireland in June 1809, Ireland to Canada in April 1812. They were still in Canada in January 1815 when my transcription ceased.
