As Vinegar Joe Stillwell said after being ejected by the Japs from Burma, ""I claim we got a hell of a beating. We got run out of Burma and it is humiliating as hell. I think we ought to find out what caused it, go back and retake it."
Note the "find out what caused it" phase. Stillwell didn't propose more of the same, fighting the same way to produce the same result simply out of a refusal to submit.
Fighting to the last man may be noble and brave, but it won't win the war. I propose we figure out why we're losing the battles, develop new strategies and tactics and counter-attack.
I recommend we stop implementing Einstein's purported definition of insanity, trying the same things over and over and expecting different results.
