Question: When did pakistan won olympic gold medal in hockey for the first time?

It fielded what has since then often been considered the best hockey squad ever led by captain Tariq Aziz with Saeed Anwar, Khalid Mahmood, Gulraiz Akhtar and Tariq Niazi. Even though Rasool had retired, this team was still a force to be reckoned with. They won all six of their games—against Kenya, Great Britain, Malaysia, Australia, France and the Netherlands during group play, and against West Germany in the knockout round. Pakistan made the final for the fourth straight Olympics, and won the gold medal, as they had in 1960, this time by defeating Australia, 2–1 with goals from Muhammad Asad Malik and Abdul Rashid. Rashid was the top scorer for Pakistan with seven goals; Tanvir Dar finished with six goals.
