The problem is not my expectations, but Plutarch
It still remains that Plutarch is much closer to the time era, and if you want to disregard his statements, you might as well disregard the statements of all historians from that era.
You dont throw the baby out jsut the bath water. he was undoutably accurate in that Rome suffered it worst defeat ever. But when his fiction doe snot match the other evidence you sid ewith the evidence not the fiction
1- If the Romans were nailed to the floor so to speak how did Giaus rally 10,000 of them and manage a sucessful retreat?
2- you don't shoot arrows 6 at a time
3- Giaus later defeated the very same Parthian troops (minus thier general) in Syria
As for wounding vs. piercing arrows, your ideas of arrow balllistics is really weird. The arrows are indeed shaped for flight, the wounding part is only at teh back of the arrow, so it tears flesh when pulled. On the three sided bolt, it is the three pointed corners tha provide the area of contact, not the three faces. Try working with some nails once.
Your grasp of the situation on arrows vs sheilds, leaves alot to be desired
1- the tri-wedge shape presents a greater surface area on impact allowin gmor eof it's energy to be spread across a wider area. This is why the bodkin was a basically a nail on a shaft, to concentrate it's energy.
2- All three edges were sharpened via the sources the Han enthusiast presented. Straight edges tend to bind from friction when forced through wood. This is why saws have offset and varying sized teeth.
3- if Han bolts rendered sheidls useless sheilds would ahve fallen out of favor, they didn't so they obviously fullfilled some military use.
Let me put it this way. I doubt that any wooden shields would have stopped a metal crossbow bolt with the draw strength of 3 to 6 dan, which is range of draw strength of Chinese crossbows. Each dan is about 60lbs of draw strength, which is considered the minimum draw strength for a Chinese recurved composite bow, and a recurved bow is generally about 2 to 3 dan though some stories suggest up to 4 dan.
The higher the draw weight the more effort it takes to load, the more effort it takes to load the longer between volleys and the less mobile the formation.
Crossbows come in a variety, some have shoulder butts and gunsights. Some artist depictions of the crossbows may not be accurate because the wood would have rotten away in many ancient crossbows. As the fact that unlike the gun, the crossbow does not recoil, you can still hold it in one hand and shoot accurately.
Yes it does, and the bigger the draw the more the recoil, or would it be forcoil? Either way when the tension is released and the bows snaps forward there will be the transferance of energy requiring bracing for accurate fire. I am I am sure many others here have actually fired crossbows.
Technology
first you say the Han are superior becuase they have steel,now you say a technologically inferior army can defeat technology, which is it?
Beejay,
Thanks for the Han-soldier picture. Is this a normal infantry man (armor and weapon like)? And is his the normal crossbow? This crossbow lacks a shoulder butt ... doesn't this greatly reduce its accuracy?
No it is not accurate, the armor might be but only elite formations had metal, the rest had lamillar leather. The weapons are not possibly accurate the crossbow might be a hand crossbow but these only had a range of 80 yards and an effective rang eof much less. it wa sprobably missdrawn with artistic licence. Who ever drew that sword needs to be shown a real weapon of war. it lacks a cross guar dto protect the warriors hand sfrom enemy blows and his own momentum driving his hand forward onto the blade. You don't shod a trooper in metal and then have him cut his own fingers off.
However if the leangth is right,and based on Crobato's statements it is, then that man would ahve been slaughtere dvs the romans in close combat when tightly packed bodies prevented slashing attacks and the weapons leangth and non stabbing tip would have placed it at a disadvantage vs a legion.
