Great point, Necchi,
This is something very interesting to me in not only "how" they did something back then, but also "why" they did it.
I remember someone (maybe Doc Andy Baker?) suggesting they used the woven ties wrapped above and below the knee to support their knee's much like a knee brace does today, but I never thought about a sash being used to prevent hernia's. (Andy was a Gynecologist by profession, but even he joked about his patients initially thinking he was an Outlaw Biker when they first met him, so he had a picture of him in his buckskins put in his office. Grin.)
I was JUST old enough to have occasionally used a "Field Transport Pack" in my earliest days in the Corps in the early 70's. Between the Knapsack, Haversack, rolled camouflage "tube" and associated gear; those packs weighed between 90 and 110 lbs. They were not fun just to stand inspection with, let alone march with them. By the 90's we had the ALICE packs which were a good deal better, but still needed some improvement. So I decided to take some lessons from history and apply them to the then modern pack.
Of course I was not allowed to use the Voyageur's Tumpline for a military pack, but I stopped at RSI and had them make up a "breast strap" like the Voyageurs used and also bought a padded hip belt. I hand sewed the hip belt to the pack using leather needles and artificial sinew, so the weight of the pack was on my hips instead of my shoulders. Made a world of difference on forced marches. Funny thing was no one noticed until the third time when I wore the rig and a Major asked me about it.
The Major wasn’t being critical, but rather wanted to know why I made those modifications. So I asked him, “Sir, ever heard of the term “"Coureur de bois" or “Woodsrunner?” When he said he had not, I gave him a short history lesson and later on he asked me how I made those modifications. I told him those men had made their living off of carrying huge loads over long distances and they surely knew how to carry heavy packs. So he went to RSI and got the added gear and I showed him how to attach the breast strap and belt over one lunch hour. Our Colonel spotted us and asked what we were doing and that led to him getting the gear and I sewed the hip belt to his pack as well.
Word spread quickly and that started a bunch of trips to RSI and I forget how many hip belts I hand sewed to packs for us in Division Ordnance and the G4 section. Within a few months, most of us at least had breast straps on our packs and it was uncommon not to see one so modified.
Of course it was great to spread some knowledge of our time period in history while we did it. This was just one example of many times I used the lessons of history to make or do things better “in modern times.”
