19 American won two MoH's while a New Zealnder won two VC's (Victoria Cross with bar) for actions during combat and two British doctors also won two VC's for rescuing wounded. I don't know if this reinforces or undermines your notion that it is "easier" for Americans to earn MoH's than it is for military personnel of the British Empire/Commonwealth countries. Maybe it is just your New Zealand pride showing.
I don't see that it's particularly relevant. Double-winning is rare enough for both awards that it's not worth comparing. (I believe the laws for the MoH were also changed in 1919 so that you cannot win two of them)
3465 MoH's awarded to the 1356 VC's. Both established at about the same time. 1522 of the 3465 total MoH's were awarded during the Civil War.
Yes I'm aware of all this. The changing criteria for the MoH certainly plays a role - it used to be the only medal that could be awarded, and until the early 20th Century was awarded for all sorts of less impressive feats.
Having said all of that, it has to be remembered that the VC has been available to more military personnel in more wars than the MoH.
There are a number of factors that could contribute markedly to the difference.
-The VC requires recommendation of a regimental level officer or higher, and the action must be confirmed by three witnesses.
-When entire units are deserving of a VC a ballot is conducted whereby one soldier, sailor or airman at random is given the VC.
-The requirement that action be in the face of the enemy was introduced for the VC about half a century earlier than for the MoH.
-For some time the MoH was the
only medal a US soldier could receive, whereas the VC was specifically instituted for acts of extreme bravery.
-American culture places a much higher value on the sacrifice and efforts of their service personnel than English culture traditionally does.
So just to clear up any confusion, no I don't think the difference in numbers is any reflection that British soldiers are more courageous than US soldiers. Such an argument would be wholly without merit. If the above factors don't explain the difference entirely, the obvious conclusion is just that British and Commonwealth authorities are more reluctant to issue a VC than the US Congress is to issue a MoH - perhaps explained by the last point in the list.
