You can try offensive team with catapult (+ shield for wakizashi), or go full defensive with heavy infantry for tantou, shieldmen for wakizashi. If you keep losing troops in early nodes, it probably indicates your sword levels aren't high enough. If you must continue to grind in 6-1, you can just equip whatever dispensable troops (silver and bronze) to level up until you can safely reach 1-2 nodes before boss node.
