CWSAC description
Following the Battle of Big Mound on July 24, 1863, Brig. Gen. Henry Hastings Sibley and his men moved their camp about four miles and then rested till the next day. The morning of the 26th they set out and after marching about 14 miles, found the Sioux ready for battle. At first, the fighting was long range because the Native Americans refrained from closing with the soldiers. The Native Americans did attempt to flank the left side of the camp and run off the mules. The Mounted Rangers and infantry, though, after heavy fighting, compelled the Native Americans to abandon their intentions. Following this setback, the Sioux retreated, ending the battle. Sibley resumed his march after the Native Americans the next day. The Sioux were on the run.

logistics

supportedunresolved Sibley says there was neither wood nor water beyond the lake; the attack on the left aimed, in his view, at stampeding the mules. Crooks says the Indians sought to destroy the transportation.

Supply conditions and inferred aims from interested reports; not a return.

objectives

supportedunresolved Sibley says the Indians, after long-range firing, tried a flank movement on the left of the camp to stampede the mules; Crooks describes a desperate attack on the north front to destroy the transportation.

Aims inferred by opponents. No account by the Dakota bands was inspected; their numbers, aims and losses come from their opponents' estimates, prisoners' or scouts' statements relayed by them, or the NPS summary.

outcome

supportedpost_outcome The frozen and live results read Union victory. Sibley says the Indians, foiled, fled leaving dead on the prairie; Crooks that they left the field after a parting volley.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit.

supportedpost_outcome The frozen casualty text reads Unknown; the live field reads 10 (US 1; CS 9). McPhaill's regimental losses include a skirmish on the 26th at Dead Buffalo Lake without a separate figure (see Big Mound); no inspected report gives a loss for this action alone. McPhaill's July 24 pursuit also drove Indians from the rushes of Dead Buffalo Lake.

Original casualty returns were not inspected; preserve totals, categories, cutoffs and differences. No canonical reconciliation or casualty-based opening count; related actions must not be added without resolving population overlap. McPhaill's 31 Indians killed is not assigned between this record and Big Mound.

responsibility

supportedunresolved The frozen US commander is Brigadier General Henry Hastings Sibley. The frozen and live Native American commander is Inkpaduta (no rank; the live page tags him [CS], not adopted); none of the inspected reports names him, so his role is not established here. Sibley posted Jones's guns and Chase's pioneers and sent Taylor's company to the left; the mounted companies of Wilson and Davy and McLaren's six companies of the Sixth secured the camp's flank. Crooks credits Averill with the skirmish line and McLaren with the reserve.

Command roles from interested reports; no automatic sole credit.

strength

unknownunresolved

No inspected return establishes matched personnel at a common opening boundary. The frozen side-specific numerical strength bounds are blank (missing_numeric_strength). No figure in this pass is adopted as a simultaneous opening force.

supportedunresolved The frozen force field names the District of Minnesota and the Santee and Teton Sioux without figures; the live field reads 0. Sibley says the Indians were greatly superior in numbers; neither Sibley nor Crooks gives a figure for this action.

No figure in the inspected reports. No account by the Dakota bands was inspected; their numbers, aims and losses come from their opponents' estimates, prisoners' or scouts' statements relayed by them, or the NPS summary. None is adopted as a matched opening strength.

terrain

supportedunresolved Sibley camped on the border of Dead Buffalo Lake because McPhaill had found neither wood nor water beyond it, and posted guns on a commanding point about 600 yards in advance; the mules were herded on the lake shore.

Camp ground from an interested report; no map verification.
