"Zamzama Gun Kims Gun or Bangian wali Tope is located on Mall road near Anarkali Bazar Lahore. The Zamzama Gun, a historic cannon with a legacy spanning nearly 300 years, stands as one of Lahore's iconic monuments. Known as the “Zamzama Toup,” meaning "thunder" or "roar," this massive cannon—sometimes referred to as "Kim’s Gun" or "Bhangianwali Toap"—is among the largest of its kind in the Indian subcontinent. It was cast in 1757 in Lahore during the Durrani Empire, under the guidance of Shah Wali Khan, the prime minister of Afghan King Ahmad Shah Durrani. The cannon, measuring 14 feet 4.5 inches (4.382 meters) with a bore diameter of 9.5 inches (24 centimeters), was crafted by Shah Nazir, a metalsmith serving the former Mughal viceroy, Muin-ul-Mulk.
Originally intended for battle, the Zamzama Gun saw its first significant use during Ahmad Shah’s campaign in the Third Battle of Panipat in 1761. On his return to Kabul, however, Ahmad Shah left the gun in Lahore with his governor, Khawaja Ubed, as transportation arrangements for the cannon had fallen through. The second identical cannon Ahmad Shah had commissioned was taken to Kabul, though it was reportedly lost near the Chenab River.
In 1762, the gun changed hands when Maharaja Hari Singh Bhangi, a prominent Dhillon Jat ruler, seized Lahore’s arsenal following his victory over Khawaja Ubed. Among his conquests was the Zamzama Gun, which he and his Sikh forces renamed “Bhangi Toap.” Initially kept in Lahore Fort’s Shah Burj, the cannon was later given to Charat Singh Shukerchakia, a Sandhawalia Jat ruler from Gujranwala, as part of a share of war spoils.
Charat Singh’s acquisition of the Zamzama Gun surprised the Bhangi Sardars, who had believed the cannon’s weight would make it impossible for him to transport. Nevertheless, Charat Singh successfully took it to his fort in Gujranwala. The gun subsequently became a contentious trophy, passing through several rulers' hands and even sparking skirmishes. It was seized by the Chathas and transported to Ahmadnagar, where conflicts erupted between the Chatha brothers, Ahmad Khan and Pir Muhammad, leading to bloodshed.
The cannon eventually returned to Gujjar Singh Bhangi, who reclaimed it with Pir Muhammad Chatha's assistance. However, Charat Singh Shukerchakia soon recaptured the cannon, only for it to be seized again by Pashtun forces. A year later, Raja Jhanda Singh Bhangi defeated the Pashtuns and brought Zamzama to Amritsar. In 1802, Ranjit Singh captured the cannon after defeating the Bhangis. He then deployed it in his battles across the Punjab, using it at Daska, Kasur, Sujanpur, Wazirabad, and Multan, where it suffered significant damage during the siege of Multan.
Today, the Zamzama Gun is displayed outside the Lahore Museum, a testament to its turbulent past and the various empires and rulers it served over the centuries."

"The Zamzama Gun meaning "thunder" or "roar", sometimes written "Zam-Zammah" or "Zam-Zammeh" also known as Kim’s Gun or Bhangianwali Toap is a large-bore cannon. It was cast in about 1757  in Lahore (present-day Pakistan) during the Durrani Empire. It is currently on display in front of the Lahore Museum in Lahore, Pakistan. The gun is 14 feet 4+1⁄2 inches (4.382 metres) in length, with a bore at its aperture of 9+1⁄2 inches (24 centimetres). This gun, one of the largest ever made in the sub-continent, was cast at Lahore along with another gun of the same size in 1757 by Shah Nazir (a metalsmith of the former Mughal viceroy Muin-ul-Mulk), under the directions of Shah Wali Khan, who was prime minister in the reign of the Afghan King Ahmed Shah Durrani. The gun was used by Ahmed Shah in the battle of Panipat, in 1761. After the battle, on his way back to Kabul, he left it at Lahore with his governor, Khawaja Ubed, as the carriage that was supposed to take the gun to Kabul was not ready. The other gun he took with him but that one was lost in passage through the Chenab.
In 1762, Dhillon Jat Ruler Maharaja Hari Singh Bhangi went into battle with Khawaja Ubed. Bhangi attacked the then-village of Khawaja Said two miles (3.2 km) from Lahore (now part of the city of Lahore), where the Mughal governor Khawaja Ubed had his arsenal, and seized his artillery, arms and ammunition. Amongst the guns captured was the Zamzama Gun itself. It was renamed by its Sikh captors Bhangi Toap.
For the next two years, it lay in the Shah Burj of the Lahore Fort. Thereafter, Raja Lehna Singh and Maharaja Gujjar Singh Bhangi got hold of it and they gave it to Sandhawalia Jat Ruler Charat Singh Shukerchakia as his share in the spoils. The Bhangi Sardars thought that Charat Singh would not be able to carry this gun with him and it would remain with them. Contrary to their expectations, Charat Singh successfully carried this gun to his fort at Gujranwala.
From Charat Singh, Zamzama was snatched by the Chathas who took it to Ahmadnagar where it became a bone of contention between the brothers Ahmad Khan chatha and Pir Muhammad chatha. In the fight that ensued, two sons of Ahmad Khan and one of Pir Muhammad were killed. In this fight, Gujjar Singh Bhangi sided with Pir Muhammad. After the victory, the gun was restored to Gujjar Singh. After two years, the gun was wrested by Charat Singh Shukerchakia from whom it was once again snatched by the Pashtuns.
Next year, Raja Jhanda Singh Bhangi defeated the Pashtuns of Chatha and brought the gun to Amritsar. In 1802, Ranjit Singh, after defeating the Bhangis, got hold of the gun. He used it in the battles of Daska, Kasur, Sujanpur, Wazirabad and Multan. In the siege of Multan, the gun was badly damaged."
