A Champ pilot reported a bounced landing and attempted go around that resulted in an off airport landing.

Narrative

I departed to the south and headed to the north to make a full stop landing and departure at a nearby airfield and a return back. I made a normal approach into the airfield landing to the north east. I was on a stabilized approach with normal approach speed for a normal landing and for an unexplainable reason the aircraft hit hard and bounced. We bounced in such a way that it was not possible to save the landing the prudent thing to do was to do a go around. During the go around I added full power and pushed in the carb heat. At the end of the runway there is a house; incline hill; and power lines. The aircraft was not climbing enough to clear the power lines. I pulled back on the stick to clear the lines. While clearing the lines the aircraft entered into an imminent stall. I lowered the nose to recover. During the recovery I noticed trees in front of us that I knew we would not clear. I elected to set the aircraft down in the swampy area versus impacting the trees ahead. During the roll out I set the aircraft on the belly secured the fuel and magnetos and evacuated my passenger from the rear seat and proceeded to the road to the south west of the aircraft. Although a ambulance was summoned neither my passenger or I needed immediate medical attention approximately five minutes later the local police department; ambulance; and fire crew arrived.
