The Demolition of the Harmandir Sahib:

In April 1757, Ahmad Shah Durrani raided Northern India for the fourth time. While he was on his way back to Kabul from Delhi with young men and women as captives, the Sikhs made a plan to relieve him of the valuables and free the captives. The squad of Baba Deep Singh was deployed near Kurukshetra. His squad freed a large number of prisoners and raided Durrani's considerable treasury. On his arrival in Lahore, Durrani, embittered by his loss, ordered the demolition of the Harmandir Sahib (the "Golden Gurudwara"). The shrine was blown up and the sacred pool filled with the entrails of slaughtered animals. Durrani assigned the Punjab region to his son, Prince Timur Shah, and left him a force of ten thousand men under General Jahan Khan.

Baba Deep Singh, 75 years old, felt that it was up to him to atone for the sin of having let the Afghans desecrate the shrine. He emerged from scholastic retirement and declared to a congregation at Damdama Sahib that he intended to rebuild the temple. Five hundred men came forward to go with him. Baba Deep Singh offered prayers before starting for Amritsar: "May my head fall at the Darbar Sahib." As he went from hamlet to hamlet, many villagers joined him. By the time baba Deep Singh reached Tarn Taran Sahib, ten miles from Amritsar, over five thousand Sikhs armed with hatchets, swords, and spears accompanied him.
