Gentlemen,I've read, that NAs were scared of Infantry Troops.If it's true,why were they?.Best wishes Trish.
Trish, I don't know to what degree the Indians were "scared" of infantry; but if they tended to avoid contact with "walk-a-heaps" it was primarily due to the superior range of the Springfield .45/70 rifle as opposed to the cavalry carbine. The "Long Tom" as the rifle was nicknamed, had an effective range of around 1200(?) yards as opposed to the 600 yd. or so range of the carbine. Compare that with the Indian favorite Henry/Winchester repeater with a measly 200 yd effective range. The popularity of the Henry/Winchester was due to its light weight and its ammo; same cartridge could be fired in revolver, thus the cowboy or Indian only needed one caliber of ammo.
Donn't recall the source but one Lakota or Cheyenne warrior commented that "walk-a-heaps diggem hole....Injun can't do nuttin' widdem...." Further, unless they were mounted infantry, there would be no horses to capture. There were a number of fights between plains Indians and infantry; Miles' fall and winter campaign featured such. Interesting footnote is that during the Nez Perce War elements of the Seventh Cavalry carried the Springfield rifle and not the carbine.
