larger force with bow/arrows and horses aren't impressed with your swords and armor

storms aren't impressed with your arrows and horses and ships.

Therefore measure in terms of five things, use these assessments to make comparisons, and thus find out what the conditions are. The five things are the way, the weather, the terrain, the leadership, and discipline.

The Way means inducing the people to have the same aim as the leadership, so that they will share death and share life, without fear of danger.

The weather means the seasons.

The terrain is to be assessed in terms of distance, difficulty or ease of travel, dimension, and safety.

Leadership is a matter of intelligence, trustworthiness, humaneness, courage, and sternness.

Discipline means organization, chain of command, and logistics.

Every general has heard of these five things. Those who know them prevail, those who do not know them do not prevail.

Therefore, use these assessments for comparison, to find out what the conditions are. That is to say, which political leadership has the Way? Which general has ability? Who has the better climate and terrain? Whose discipline is effective? Whose troops are the stronger? Whose officers and soldiers are the better trained? Whose system of rewards and punishments is clearer? This is how you can know who will win.

they really didn't heed or perhaps know the "weather" forecasts

As they were never a sea faring people, they made up for it through their horsemanship and became a formidable force to be reckoned with on land!
They almost destroyed the Muslim world, and they still remain a formidable enemy in the minds of the Pushtun people on how they destroyed Afghanistan and made it the way it is today i.e. the distrust of Central Asians and the hatred they put up with to survive today with their cousins Hazara, Uzbek and others.

In order to defeat Japan, the Mongols had to have set foot on the island!
