Day 0 • Curtis digs in at Little Sugar Creek • Van Dorn decides to envelop
Day 1 - Leetown • McCulloch runs into trouble • Fed Maj Eli Weston’s pickets detect large rebel force on Bentonville Detour • Curtis sends Osterhaus’s division to intercede • Both McCulloch and McIntosh killed • Confed Hebert makes unsupported attack • Fed Davis Division moved up to stop him • Confed Pike does little as rest of Division awaits orders which never come • Hebert and Pike withdraw
Day 1 – Elkhorn Tavern • Curtis • Grenville Dodge had also detected Confed movement at Three Corner Church; reasons Confeds have also come down Telegraph Rd • Curtis slowly figures out is being enveloped • Sends Carr’s Division to Elkhorn Tavern who runs smack into Van Dorn • Dodge on his own initiative moves up his brigade to Curtis HQ • Curtis sends Dodge to reinforce Carr and then redeploys his whole army to face North rather than South • Van Dorn • Uncharacteristically pauses coming out of Cross Timber Hollow • Loses communications with McCullough, looses track of ordinance wagons • Assumes role of brigade commander and directs accurate artillery • His infantry eventually push federals back at Elkhorn Tavern but use up a lot of ammunition
Day 2 – Elkhorn Tavern • Van Dorn • Concentrates forces for attack • Then realizes artillery and troops will run out of ordinance • Decides to withdraw even as battle begins • Slips away to the south east on Huntsville Rd • Curtis • Sets up for the kill with deadly accurate artillery barrage • Sigel carries out tremendous right wheel • Whole Fed Army charges at the same time • “Dot was lofely”
Reasons for Confederate loss • VanDorn in overdrive, ignored logistics • Obsession with speed wore down his troops • Did not assemble efficient staff • Assumed role of brigade commander in battle • No communications with division commanders • Not well served by subordinates • Loosing track of ordinance wagons was criminal • Mistakenly though Curtis would not fight, so tried to envelop • Could have just done flanking manoeuvre and come in from Leetown against Curtis rear
Reasons for Federal Win • Curtis generally made the right decision • Decided to stand and fight rather than run • Counterattacks kept Confed army divided • Kept forces in reserve until threat clear • Well served by subordinates and staff except for erratic Siegel • Left tactical matters to division commanders and remained in control • Used interior lines to deploy forces • Timely communications with Div commanders
Aftermath • Losses • Fed 1384 (203 killed, 980 wounded, 201 missing) 13%; Confed 2000, (15%) • Missouri is saved for the Union • Army of the Southwest marched all the way thru Ark to Helena on Mississippi subsisting on the land • Curtis never got the recognition he deserved • Army of the West withdrew into Mississippi and never fought again • Van Dorn decides to join P.T. Beuregard but can’ t get to Shilo in time • Loses at Corinth, filanders and is shot by enraged husband
What Could Have Been • If Confeds had won, would have rampaged around Missouri doing a lot of damage • Likely would have reached St Louis, and then Illinois • Halleck would have had to pull thousands of troops and supplies off the river campaign • Grant would likely have not been as successful…
