There is a time when one must realize their weakness' and change their stratagy if they are to survive. “The greatest victory is that which requires no battle.”

“Thus we may know that there are five essentials for victory:
1 He will win who knows when to fight and when not to fight.
2 He will win who knows how to handle both superior and inferior forces.
3 He will win whose army is animated by the same spirit throughout all its ranks.
4 He will win who, prepared himself, waits to take the enemy unprepared.
5 He will win who has military capacity and is not interfered with by the sovereign.”

Great results, can be achieved with small forces.”

“It is only the enlightened ruler and the wise general who will use the highest intelligence of the army for the purposes of spying, and thereby they achieve great results.”
― Sun Tzu, The Art of War
