On this date 150 years ago, General John Fremont's inaction in bringing relief to Colonel Mulligan's troops at Lexington, Missouri, led to the enforced surrender of those forces after more than a week of siege. General Sterling Price, the Confederate officer who led the offensive, lost 25 men out of his 18,000 troops, while Mulligan's force of 3600 Federals was reduced by 39 fatalities. Because of Fremont's failure to send reinforcements, the general received further criticism of his already questionable behavior in handling matters.
