Thanks fearn, I'll look into those... and if anyone else has input, I'm all eyes/ears
I remember the Mandarin Duck formation from General Qi Jiguang... Supposed to be inspired by southern ethnicities and their method of warfare. It seems to have consisted of 12 people, 11 in combat, and 10 main combatants.
1 squad leader w/ flag
2 sabers and rattan shields
2 multiple tip spears
4 long spears
2 tridents
1 cook/porter
Looks like 1 saber to 4 spears (of varying types).
But that sheds no light on the use of baat jaam do / butterfly swords, bows, and firearms amongst the southern Chinese. the sword to spear ratio of 1:4 is probably about right, maybe the ratio was even greater like 1:10 or something.
