16 months later... :o
Triage - the origin, from Napoleon's surgeon-general Larrey, was aimed at
- returning troops to this battle
- returning troops to this campaign
- those who would no longer be useful as soldiers in a reasonable time period
Using a more naval example, this is why Nelson was passed over after being fatally wounded at Trafalgar - his wound was clearly mortal and so the surgeons focused on those they could save. Similarly, Britain rationalised their ship production during the war, suspending major warships for the most part in favour of smaller and faster to build escorts.
On a semi-related note, I listened to a good podcast just recently on ten Great Admirals who can teach about traits and character interviewing retired USN Admiral James Stavridis
https://radiopublic.com/history-unplugged-podcast-WDpvpEHis list of ten admirals is not without criticism of those he describes, for example Drake was a pirate as well as a patriot while Nelson might have been an excellent leader of men but could be both a snob (see the description of his only meeting with Wellington as described by Wellington!) and had interesting personal morals. Nimitz is named in the list as well and comment is made on how he took command of the US Pacific Fleet not on the deck of a magnificent battleship but on a submarine!
I would recommend the podcast as interesting and Stavridis is a good speaker.
