War Game writers challange (S.A.V.E.)

Ok so the scenario goes like this: You are a secret agent in world war 2 and you are deep in the enemy trenches in Germany behind enemt lines. You have a hangun with 6 bullets left and a stick grenade. Across the field of battle you spy a bunker with a machine gunner inside who is unloading on your comrades. You need to stop this man. Bombs burst to your left and right, planes fly overead and the sound of a panzer tank is getting too close for comfort. Ducking back into the trench you whipe the sweat from your brow. You hear a voice in English say "It's me Jimmy, so what do we do now that we are in so far? Should we turn back, man this is deep!" You sigh as you survey your route one last time. There are four soldiers guarding the bunker with a machine gunner and sand bags turret to it's right and two men to the left who appear to be fixing a radio and calling in orders for air strikes. your trench leads straight to the right of the machine gunners and cuts left under neath the front of the ridge they are on and leads you to the well and inside the bunker. "Ok Jimmy, here is what we do...".

Alright creative writers it is your turn to finish the story. What do you do?
