can you name any US generals that routinely threatened confederate troops with "no quarter?"
In Mo (and KS), where lawlessness prevailed, from early in the war Union military authorities adoped 'no quarters' policies to deal with the exponents (both partisan rangers and guerrillas) of irregular warfare there.
On Mar. 13, '62, M-G Halleck issued General Orders No. 2 to U.S. forces operating in MO, that in part stated, ...".....Maj. Gen. Sterling Price has issued commissions or licenses ..... in this State ..... to raise 'guerrilla forces' ..... every man who enlists in such an organization forfeits his life and becomes an outlaw. All persons are hereby warned that if they join any guerrilla band they will not, if captured, be treated as ordinary prisoners of war, but will be hung as robbers and murderers. Their lives shall atone for the barbarity of their general,"... (See '
OR': Vol. 8, @ pp 611-12).
On a similar vein, advising on tactics to employ against Confederate partisan rangers fighting in the same region, Union M-G Samuel Curtis in a correspondence to subordinates on Sep. 29, '62, stated, ..."They deserve
no quarters; no terms of civilized warfare. Pursue, strike, and destroy the reptiles, and report to these headquarters as often as possible."... (See 'OR': Vol. 13, @ pp. 688-89).
Regarding relevant events in TN, preceding the 'Fort Pillow Massacre'.
In west TN, Col. Hurst and his 6th. TN (Union) Cavalry summarily executed on the spot several captured officers and troopers of Forrest's command, apparently acting on orders issued on Jun. 17, 64, by Gen. William Sooy Smith to 'grub up' west Tennessee.. (See '
OR': Vol. 32, Part 2, @ p. 124).
In yet another example. Lt. Col. James Brownlow, commanding the 1st. TN (Union) Cavalry, apparently established a practice of 'no quarter' by Federal cavalry operating in TN at the end of '63. In his report following a mounted skirmish that occurred at Yankeetown, TN, Brownlow states, ...'I would take no prisoners"... ('
OR': Vol. 31, Part 1, @ p.591).
Indications here are: Seems some Union mounted units operating in MO and west TN from '62 through to '64, at least, may have been practising 'no quarter' in armed engagements with the enemy, following orders received from the top.
