Good fun from Monk this morning!
A few clues kept me pondering for a while, but overall a fun and accessible puzzle. The paired words on the grid’s edges form common terms when put together. Not sure if there is a further connection?
Many thanks to Monk!

A (area) + D (dies) + ULT (in the last month)
ULT is an abbreviation of ‘ultimo’, from Latin, used to mean ‘last month’
C (about) to cut (IN DUE TO)* (*false)
TD (Chad, country ISO code) imports E (European)
‘Ted’ in this context is a bit archaic – it is a verb meaning to spread/ted hay to dry it out
(REEL IN and CATCH)* (*fighting)
A rooster, originating in Chaucer’s The Canterbury Tales, becoming a popular literary character
GARB (clothing) + LED (went first)
(IN< (<back) + H (hotel, NATO alphabet)) having EVEN< (just, <gone round)

I think we are looking at E for East, Afghanistan being a country (presumably) East of us
(AND GLUTEN)* (*nuts)
ARM (weapon) hidden in (CAN (jail) + U (uniform)) – on the contrary (i.e. flip the clue instruction so CAN + U are hidden in ARM)
[go]I[ng] [un]D[er] [ke]E[els] (essentially)

(O (nothing) in (SALVADOR [Dal]I (‘s latest) + O (old))* (*rubbish)

POD (group of pilots perhaps) + G[reed]Y (extremely)
Referring to pilot whales, with POD being the collective noun
DO (party) + T (time)
The northeast quarter was my Waterloo. Having confidently entered EEL for 7d didn’t help. ARCANUM, ESTORIL, TED & SEDGEMOOR were all new to me. I was unsure of ELAND — not my favourite clue.
All else fell into place and was enjoyed.
I hadn’t heard of a CHANTICLEER or the battle, but was able to figure them out from crossers and a little help from Google. I got excited when I spotted the two word phrases around the edges, but I don’t see any theme related to them.
Couldn’t parse HIGHS but I knew it was right from my Geography lessons many years ago.
Good fun from Monk today. The three letter clues were the trickiest. Nho OBI nor TED although IDE is an old favourite in crossword land.
Thanks Monk and Oriel for a model blog.
