What new tech did Genghis Khan posses?
Hi,
The Mongol Composite bow------had the advantage of the longest shooting range of any bow for centuries to come----.
And to top i t off----the archer would use it on full gallop from the back of his / hers horse----.
Whereas---the like of english long bow---one end had to be planted on the ground----and still it was weaker.

The Mongol bow is not as large and long as the English one, but it is vastly more powerful. The draw weight of an English longbow averages around 70-80 pounds, whereas the Old Mongol bow had a pull that, according to George Vernadsky, averaged at around 166 pounds. Chambers states that the pull varied from 100 to 160 pounds. This seeming discrepancy certainly reflects the fact that draw weight varied with the strength of the user, and with what use the bow had been made for. As could be expected, there was a considerable difference in shooting range. Whereas the English longbow could shoot at distances up to 250 yards or around 228 meters, the Mongol counterpart can hit its target at 350 yards or 320 meters and, if the archer is well trained for the task, even beyond that.
There are people who claim that the Old Mongols could shoot and hit their target over truly astonishing distances. Gongor Lhagvasuren, Deputy Director at the Mongolian National Institute of Physical Education, has written an article called "The stele of Chinggis Khan." There, Lhagvasuren refers to an ancient inscription on a stone found in the basin of the river Kharkiraa, a left tributary of Urlengui river which flows into the trans-Bajkal river Erdene. The text of the inscription, supposedly dated from 1226, may be interpreted as follows: "While Chinggis Khan was holding an assembly of Mongolian dignitaries, after his conquest of Sartaul (East Turkestan), Esungge shot a target at 335 alds" (536m). Lhagvasuren draws the conclusion in his article that such feats were rather common for Mongolian archers during the 1200's, and writes: "This case illustrates the strength, accuracy and sharpness, physical prowess of the Mongolians who lived more than 700 years ago." Whether or not we find it likely that Mongolian archers could regularly hit their targets at the distances Lhagvasuren claims they could, there is no question that they and their and bows are outstanding in all of archery's history.
When we take a closer look at the Mongolian bow, we see that it is an intriguing construction indeed. The backbone of the bow is a wooden frame, which will typically be birch, because that wood is resilient and is also readily available. The total length of the frame is 150-160 cm. When the bow is unstrung, it looks like a semi-circle with a beautifully curvaceous shape, but when a string is attached the whole thing is stretched out so that its limbs are bent inward. Even so, these limbs with string attachments are bent slightly away from the archer, forming a double curve. It is this double curve that delivers explosive acceleration and awesome velocity to the arrow. From these limbs or bends of the bow behind the string attachments where the impact is greatest, the frame is covered with elongated and flattened pieces of mountain sheep's (or other wild or domesticated ungulate's) horn or/and bone which adds snapping power to the resilient wood in the frame. These hard parts form a layer that covers the whole area of the so-called belly, which is the part between the grip and the limbs. Chambers describes how the back parts of the bow, nearest the archer, were those covered with horn and/or bone while the sinew layer was applied to the outer side.
The reader will have noticed that I use the term horn and/or bone. This is because the precise details of how the bows were built could vary over the Siberian area, although the main features are clear. The bone elements, when added, are no more than a small part at the center of the bow, and may originally have served mainly ornamental and possibly magical purposes ".

As we understand, high-quality Mongolian bowmaking is certainly a most impressive craftsmanship. When the wooden frame, and the horns/bone parts are ready, the sinewing can take place. First the tendons have to be dried. After that, they are crushed until they form a mass of loose fibers. Next, this mass is mixed with fish glue to form a solid but not rigid layer. It is important to apply the correct thickness and amount of sinew, and it is done in a two-stage process with some days in between. Too little makes the bow weaker, too much would make it stiff. When completed the layer of sinew could be as thick as a human finger before drying. Sinew has a peculiar quality: Unlike other materials, its strength increases when subject to stretching or impact. This form of elasticity is a property stemming from the molecular structure of the protein of tendons (collagen), and can be seen as another striking demonstration of the innate superiority of natural solutions and materials. When used in a Mongolian composite bow, the effect is that as the horn plates in the front snap back to their former shape, the sinew layer in front contracts in the same split-second, adding further acceleration to the shot as the arrow is propelled forward.
