He took a pledge before going to battle field that he will give his head only before his Guru Ramdas (4th guru of Sikh religion) at golden temple but on the way, during the clash, one of the Mughal commanders, Jamal Khan, attacked Baba Deep Singh Ji. As they fought, both men swung their weapons with great force, leaving both of their heads separated from their bodies. After seeing this scene, a young Sikh warrior called out to Baba Ji, reminding him of his vow to reach Harmadar sahib or golden Temple. Upon hearing this, Baba Deep Singh Ji immediately stood up, holding his severed head upright on his left palm while holding his Khanda (Two edged sword) in his right hand. He then continued fighting (with strength derived from the recitation of JapJi Sahib) and moving towards Sri Harmandar Sahib. Upon seeing the sight of Baba Deep Singh’s headless body tearing through their numbers, most of the men in the Mogul army fled away in terror. Baba Deep Singh was able to continue fighting and fulfilled his oath on finally reached Sri Harmadar sahib there he bowed and lay his head on the parkarma (rectangular walkway) of this sacred Gurudwara. The Sikh Army continued to fight the fleeing Mughals until victory was achieved. Baba Deep Singh ji is remembered by all Sikhs as a brave and courageous martyr with an unflinching dedication to the Sikh principles.
This scared place where every Sikh has bowed his head in due respect to babaji is removed by SGPC (Akalis) because they objected bowing heads of Sikhs other than Guru Granth sahib ji but forgot they deserve to honor their martyrs also and history teaches the nations of their glorious past to which these ignorant ignored.
Waheguru ji ka khalsa waheguru ji ki fateh !
