I put together these battles that have in common an Eurpean (or with European standards) army versus an unconventional/different enemy.
Well let's have a look to the numbers:
1876 LITTLE BIG HORN 211 US troops vs 2000 Indians: 1 US troops every 9,5 indians (Indian Victory)
1879 ISANDLWANA 1.800 british vs 20.000 Zulu = Zulu victory; proportion 1british every 11 Zulu
1879 RORKE'S DRIFT 139 British vs 4000 Zulu: 1 British every 28,7 Zulu warrios
1887 DOGALI 500 Italians vs 10.000 Abyssinians:
Abyssinians victory; proportion 1 Italian every 20 Abyssinian
1996 Adowa: 17.700 Italian vs 120.000 Abyssinians: 1 Italian every 6,7 Abyssinian warriors. (Italian deafeat)
Elements in common: all the not European amry were also armed with rifles, mostly the Abissinians.
The 2 battlle of Little big Horn and Dogali presented the same problem: patrols: The Italians had 80 each and the US Cavalry had 100 each while at Rorke's drift the British had plenty of patrols.
The latest is the only battle with good defensive position (in comparation to Dogali for instance or Little Big horn)
So the question is: the defeats depended on patrols, defensive positions or quality of the men ? (this is because some comment about Italian soldiers… I read)
