To make his story even more plausible, I've read some statments by Indians that were present or at least claimed to be present, that some number of the troopers horses bolted straight towards them and at least one they think made it through without being killed. Who can say for certain, it almost sounds reasonable. However, even if he did survive he never saw enough of the battle to to cler up any mysteries.
Douglas W Ellison in 1985 authored "Sole Survivor an Examination of the Frank Finkle Narrative" which was the first account taken from the various newspaper interviews that Finkle and his family had given. The Real West article that trooper has mentioned was taken primarily from Ellison's research and as with most accounts of Custer's final fight there are as many evidential holes in the Finkle story as there are evidential accuracies.
So what do we know about the final 30 minutes of C Troop based on archeological evidence such as bones, bodies (markers), artifacts, shell casings and Indian accounts?
After the attempt to cross or feign an attempt across the river there was one last rendezvous position of all of Custer's battalion before C Co launch an attack to clear Calhoun Coulee of Indians while
E; F; I and L move north to either gain higher ground or find an escape route. But C Co come under intense fire from Lame White Man and his warriors and fall back in disorder now pursued by hundreds of mounted Sioux and Cheyenne. Company L under Lt Calhoun throw out a skirmish line to cover C Co's retreat to Calhoun Hill but are engulfed by Gall's warriors attack from the southern approaches and the position swiftly collapses amid fierce hand to hand fighting with the few survivors fleeing to Keogh's position on Custer Ridge.
Finkle never confirmed at what moment he left the action/battle but the collapse on Calhoun Hill- according to Indian accounts- would be the most accurate location for where Finkle would have began his "escape". He stated that a bullet struck the butt of his Springfield carbine throwing the barrel against his forehead the blood of this facial wound temporarily blinding him. He quickly receives two more bullet wounds one to his abdomen/side the other to his right heel while his horse takes a bullet to it's flank causing it to bolt straight through the Indian lines surprising the warriors.
Rain in the Face the Hunkpapa war chief stated in 1894 "One long knife escaped laying across his pony (slumped and wounded? maybe) as it ran passed us".
We also know now that others broke through the cordon Corporal John Foley raced away pursued by a band of warriors who finally ran him down someway from the battlefield. Another may have been Lt Harington second in command of C Company whose body was never found and Trooper Nathan Short made it as far as the Rosebud River before both he and his horse collapsed dead their skeletons being found years after the fight. All feasible as most of the 7th's mounts coming from Kentucky could easily have outrun the shorter legged Indian pony-depending of course on their condition after being in the field for some considerable time.
Ellison's account comes down firmly on believing Finkle's story highlighting such evidence as Finkle's accurate knowledge of the terrain and topographic descriptions of the valley area; the identical signatures of Augustus Finckel's enlistment papers into the 7th cavalry in 1872 and Frank Finkle's in 1921; Sergeant Finckle's best friend in the 7th was Sergeant Charles Windolph of Benteen's H Company and a survivor of the fight on Reno Hill returned to the Custer battlefield to specifically look for his friend's body but couldn't find it; the discovery of a C Trooper's horse by Lt Godfrey some way from the battlefield etc.etc.
And then of course you have the doubters who refute Finkle's story listing their evidence such as Finkle's unshakeable account that he held the rank of trooper sometimes corporal-never a sergeant; he rode a roan where all C Company's mounts were sorrels in accordance with Custer's insistence of all his company's horses to be in perfect uniformity; evidence from Sergeant Kanipe who brought Custer's first order to Benteen stating that he recognized Sergeant Finckel's body lying next to Sergeant Finley etc.etc.
Like I said before-Who Knows? Good story though and Ed is right if he indeed was a survivor and broke out at Calhoun Hill he would have not seen anything of Keogh's final fight let alone Custer's.
