The Polish pilots of the Russian-made Mil Mi-24 "Hind" helicopter-gunships dived and banked overhead. The firing from the ridges began to die down and ended when a howitzer found its mark, to cheers from the troops.
By the standards of this vicious war, this was a minor skirmish. But it showed how difficult it is to gauge success in an insurgency. The Taleban have been driven back from here but the assault announced they were alive to fight another day.
What happens in districts like Zana Khan is of intrinsic importance as the West charts its exit strategy from this long and costly war.
This week, the US head of international forces in Afghanistan, General John Allen, said the Taleban were in retreat, their leadership in Pakistan divided and dispirited foot soldiers deserting in large numbers.
Afghan security forces, he and other senior US and British officials insist, will be able to maintain the government's writ across the country with help from abroad.
Operation Shamshar was aimed at hitting four insurgent positions in Zana Khan, a sparsely populated but vital area near Highway 1, the route that takes people and goods to market.
"We are fighting ghosts. They shoot at us and they disappear and hide away. It's not easy," said Major Krzysztof Wojcik, a Polish officer mentoring the Afghan forces, as he sheltered in a "mine-resistant ambush-protected" armoured vehicle.
"This is a never-ending story. We have carried out this same clearance operation five times now but they keep coming back.
"This low-intensity battle will continue if there is no political solution. We already know there is no military solution to this; the two sides need to sit together and talk and form a government.
"What is happening now is because the Taleban knew the shura was taking place. They wanted to attack the governor and the journalists."
A force of 400 Afghans and Poles took part in the Afghan-led operation, with General Daoud Warfada Shah in charge.
"The Taleban are cowards," he said. "They do not dare to fight us face to face. They are thieves in darkness, trained to bomb and to murder in a neighbouring country. It is our duty as Afghan soldiers to protect our citizens and take control of these villages. Most of the Taleban we are facing now are not Afghans, but Pakistanis."
But as local journalist Jamshed Ghawse, 31, pointed out: "The problem is that the foreign troops, and our security forces, have never stayed for very long. They come along and then they go after a while. When the Taleban come back, they take revenge on all the people they blame for co-operating with the government.
"Sure, you have some Pakistanis coming over and they are very bad people. But you have a lot of local people as well who are Taleban. Villagers from here go to the Taleban to get disputes settled because it is cheaper and quicker than going to the courts. They deal strictly with criminals. But if the government was effective and stayed in the area, the local Taleban would give up their guns."
The Governor of Ghazni, Mohammed Musa Khan, says: "There are three kinds of Taleban. Those who are driven to it because of injustice by officials, those who are driven to it by poverty, and those who are being used by our malign neighbours in Pakistan and will not change. We must look after the first two; the third we must fight. In the meantime, we must help the people and educate the young."
