When Banda Singh Bahadur heard about the shahidis of Sahibzadas at Sirhind, he became very upset. He went over to Guru Gobind Singh jee and asked his permission to punish the tyrants who had committed this inhuman act. Guru Sahib granted him this permission and dispatched him to Punjab along with 5 Singhs.
Banda Singh because of his experience with meditation, very soon became a Sikh of high spiritual stages. Such was his Kamayee that whoever looked at him bowed to him. Banda Singh was very humble person and he called everyone by the prefix "Singh", whether Sikh, Hindu or Moslem. He went up to the present day Haryana and sent letters and hukamnamas to all the Sikhs around to come and see him wearing 5 weapons. Soon he had a substantial amount of people as his army.
His army consisted of three kind of people. Firstly true Sikhs who wanted to do sewa of Panth and estabilish Sikh Raaj. Secondly salaried employees and thirdly oppressed peasantry and dacoits who joined him for the sole purpose of looting, taking revenge and making money. Most of the atrocities and plunders of the towns he conquered were done by this third category. Banda Singh was aware of this category but he needed as many people as possible to fulfill his aim of punishing the tyrants.
Anyway after conquering and punishing several towns like Samana, Sadhaura, Baba Banda Singh now turned to conquer Sirhind and punish it's governer Wazir Khan. After the powerful attack from Wazir Khan on the advancing Sikh armies, the second and the third category fled the battlefield. The Sikhs held ground for sometime but they started to move back as they were greatly outnumbered. At this moment Banda Singh himself came in the battlefield and fell upon the enemy. The Sikhs eventually conquered Sirhind. When Sirhind was conquered Banda Singh appointed Sardar Baaj Singh as the governor of Sirhind.
Bhai Baaz Singh was a very strong and brave Sikh. His bravery and fighting skills were famous far and wide. So much was his name that even the king of India had heard about him. He defeated the most strong and skilled Pathaans and Moslems in one-on-one fights in the battlefields.
When Bhai Baaj Singh was caught and brought to Delhi, he remained in high spirits and could be heard singing Gurbani loudly and saying Vaheguru Vaheguru all the time.
The following conversation and incident has recorded in the writings of Moslem and English writers who eye-witnessed the incident that took place.
The king of Delhi at that time was Farukhsiyaar and as he had heard about Baaz Singh he asked a group of Sikhs brought before him to be killed, "Which one of you is Baaz Singh", asked the king. "I am Baaz Singh the humblest servant of my Guru", replied Baaj Singh in high spirits. "I heard you are very brave and strong. What can you do now ?"
"Why don't you open my hands and feet and I will tell you what I can do", challenged Bhai Baaj Singh.
The emperor thought that what can a hunger-stricken person do amidst so many of his strong soldiers. So he ordered that his chains be opened.
As soon as the soldier opened his chains in feet, Baaz Singh like lightening grabbed a sword from a soldier nearby and killed 7 soldiers by the time he was caught and overpowered. This happened so fast that no one got time to think. The king ran for cover saying "Tauba Tauba, khudaaya Khudaaya". When he was caught, the king ordered him to be executed immediately.
We have to think that what power was it that prompted Baaj Singh to act like this. That was the power of Naam and bhagti that he had done. Otherwise a normal person becomes half dead if he or she does not eat for one day only. But Dhan Bhai Baaz Singh who had not eaten properly for the last 9 months and still managed to put up such a show.
My head bows before Bhai Baaz Singh who lived a warrior and died a warrior. If we can become even 1/10th of what Bhai Baaj Singh was, we would have no problem estabilishing any Raaj Bhaag.
