Cacophony Scamp and Gornog, The Red Reaper

Context: I control [[Gornog]] and attack with [[Cacophony Scamp]], my opponents control lets say 5 Cowards. Cacophony Scamp is a 6/1 while attacking due to Gornog's ability.

If I choose to sacrifice the Cacophony Scamp when it deals combat damage to an opponent, using its first ability, how much damage does Cacophony Scamp's second triggered ability deal? Is it 6 damage, or have we left combat after damage is dealt and the Scamp is no longer considered to be an 'attacking Warrior' for Gornog's purposes, and it only deals 1 damage?
