Court-Martial date…

[Iain...]

Hi All…
Can someone confirm the second date indicated on this Court-Martial snippet. 
AWOL…, absent without leave on the day of the Battle of Waterloo, 18th of June 1815. 
Can someone confirm the date the man returned to the battalion ?   
Note, the Court-Martial was on the 20th of July 1815 in Paris.

"17th instant" - "instant" being the month the record was written. (July?)

Thanks Geoff..., yes.   However, it doesn't make sence.  I knew about 34 others from his company who were Courts-Martialled, so this makes 35.  One month to walk to Paris while being acosted by retreating French scattered throughout the region.  The man should have received a medal.
