Possible causes of loss of compression on all cylinders could be caused by; catastrophic head gasket failure on all cylinders, holes in all pistons, Piston Rings stuck in grooves in every piston, severe cylinder scoring in all cylinders, valve(s) bent / burned / adjusted too tight / seized in guides / in all cylinders, etc.
All and all the knocking you heard is not a good sign. If you are lucky it was the sound of the piston pushing the exhaust valve shut!!
Take an oil sample from the pan and look for metal. Take the valve cover off and see what it looks like under there. Is it dry?, colored BLUE?, do the valves move freely?, how tight are they?
If the cylinders are trashed there will be plenty of evidence in the oil. If the oil is not too scary perhaps you wiped out the valvetraine from the low pressure, (the cam followers could be stuck or the valves stuck in the guides). The flow of oil is restricted to the upper end so it it would be the first to go. I would think the cam would seize in the towers before the valves would stick if not lubricated, but there is always is hope.
