Well, I'm assuming the same fleet that Kublai Khan assembled to achieve victory over the Southern Song was used for operations against Vietnam and Japan. At least the seafaring portions, since the terrain of southern China would have required flat-bottomed riverboats by either navy.
Same fleet, same technology and same sailors (with Korean and few Muslim) I assumed. There're no other kind of fleet around anyway.
I'm just wondering but what did Tran Hung Dao do in the first invasion? He probably lost I would assume seeing as how the First invasion was a Mongol victory.
Uhm the first invasion was actually briefed only 3-4 months. According to Vietnamese history: Nobody known when Tran Hung Dao became a general, yet in the Fall of 1257 he was at the rank similar to Marshall, Marshal is not Supreme Commander, just a high ranking commander as far as I understand. Nevertheless his influence was high enough to made the emperor (and the crow prince) listened and bring troops to fight the Mongol head-on.
So in short the Mongol army was able to repeatedly beat the Viet (commanded by Tran Hung Dao), 'sack' the capital. That was the most successful in the 3.
Uhm but anyone here know about gunpowder weapons used by the Mongol at that period? Are they common? How effective are they? Many sources talking about fire lance, grenades, rockets, bombards or even...cannons (I guest it's just trebutche, catapult with powder ammunition)!
The Mongol fleet is also a very interesting subject... I'll read some books and do some research and see what I can find.
Yeah! And don't to share some .
I wonder if Japan and Luis Frois had something to do with that or if it was just coincidence...
He saw the Japanese training I think! Uhm about matchlock, didn't the Ming China also used similar method? There is a common picture about it
