In my opinion the army men should have digged the well not exactly of the level of pit but 6-7 feet more than the depth of pit i.e. if pit is of 60 feet deep then well should have been digged upto a minimum of 65 feet. Then parrallel tunel should be made and then upward digging can be made. In this way the child will at the most fall below 5-6 feet more down but will be safe and come down.
