Further ahead was the enemy's main position.
The main position differed a bit from the frontline; the frontline was where one would face the enemy in direct combat, whereas the main position was slightly to the rear, containing a mass of reinforcements. If the frontline couldn't hold, then troops would be dispatched forward to reinforce it. If there was a need to strengthen forces to break through the enemy's defense, that too would be done by deploying entire units of reserves from the main position.
So not far ahead was the Indian main position, where the most troops were concentrated—at least several thousand.
