1 Samuel 14:32-5, says "
32
And the people began darting greedily at the spoil and taking sheep and cattle and calves and slaughtering them on the earth, and the people fell to eating along with the blood.
33
So they told Saul, saying: "Look! The people are sinning against Jehovah by eating along with the blood." At this he said: "YOU have dealt treacherously. First of all, roll a great stone to me."
34
After that Saul said: "Scatter among the people, and YOU must say to them, ?Bring near to me, each one of YOU, his bull and, each one, his sheep, and YOU must do the slaughtering in this place and the eating, and YOU must not sin against Jehovah by eating along with the blood.?" Accordingly all the people brought near each one his bull that was in his hand that night and did the slaughtering there.
35
And Saul proceeded to build an altar to Jehovah. With it he started altar building to Jehovah.
Saul's army ate unBLED meat to not starve and no verses show God not forgiving them.
I think you need to re-read your bible.
