Disclaimer: It’s been awhile since I’ve scanned the timelines of the battle. I may be off by up to half an hour on some estimates.
On June 25th it’s the belief that the Reno fight started at around 3:15pm or so. His column retreated about 35-40 minutes later and ended up in an unorganized defensive position on “Reno Hill” probably after 4pm.
The Custer fight probably started shortly before 4pm and by 5:15 - 5:30 the Indians had wrapped up the final killing.
The one time estimate I do remember is Capt. Weir getting to Weir Point at about 5:30 and seeing the Battlefield from a few miles off and describing the Indians shooting into the ground (or finishing off the wounded and doing mop up operations).
Some historians give the Custer fight range from 30 minutes to almost 2 hours. I’d say 2 hours is way overblown considering the massive horde he was up against from the village and the Indians who had just defeated Reno to the east.
Thanks for responding.

“Crazy Horse” by Mari Sandoz
“Crazy Horse - The Life Behind The Legend” by Mike Sajna
“The Fighting Cheyennes” by George Bird Grinnell
