The below picture is cropped from an image [1] at Ancestry.com's UK, Royal Hospital, Chelsea: Regimental Registers of Pensioners, 1713-1882:
It relates to my 4th great grandfather Edmund Rouse who has been the subject of a previous Q&A here about Establishing identity of Edmund Rouse of St Clement, Cabinet Maker, Private in Napoleonic Wars and Weaver? [2]
In previous columns of the same row are pieces of information that give me confidence that this is the same Edmund Rouse that I have identified as my 4th great grandfather:
The row from which the cropped image comes is the Remarks, and I think it says:
D. D. Pagent's list / 24 June 181?
Is anybody able to work out the significance of this remark?
I am wondering whether D. D. Pagent may have been a military commander, and whether the date is perhaps the date of a battle.
In "Tracing Your Army Ancestors, Third Edition: A Guide for Family Historians" by Simon Fowler (ISBN 9781473876392), there is a section on Pension Records. From a Google Books scan [1]:
The most common entry was 'DD' for discharged dead. Occasionally the date of death is given as well.
"DD" is certainly a common remark, based on a brief perusal of the record set linked in the question. So I think it is reasonable to conclude that this is the case in Rouse's entry, and that the date relates to that as well. This doesn't look like his date of death, as he was buried months earlier, so is probably the date when the pension administrators discharged Edmund having had his death reported to them.
The "Tracing Ancestors" page [2] on the webiste of the Royal Hospital Chelsea, home of the Pensioners, says:
Out-Pensioners: those who lived 'Out', in the UK or abroad and received their pension in cash from agents around the country.
These same agents probably sent news of out-pensioner deaths back to the administrators, as the "agent's list" in the record.
