By nightfall Guru Gobind Singh was left with only five Sikhs in the fortress. These five urged him to escape so that he could rally his followers again and continue the struggle against oppression. The Guru agreed. He gave his own attire to Sangat Singh, who resembled him somewhat in features and physical stature. Under cover of darkness, he made his way through the encircling host slackened by the fatigue of the day's battle. Daya Singh, Dharam Singh and Man Singh also escaped leaving behind only two Sikhs: Sangat Singh and Sant Singh. The next morning as the attack was resumed, the imperial troops entered the garhi without much resistance and were surprised to find only two occupants who, determined to die rather than give in, gave battle till the last. Having reached safety Gobind wrote a letter in Persian prose, called the Zafarnamah (Epistle of Victory), to the Mughal Emperor Aurangzeb calling him to task as he had guaranteed safe passage to the Punjab for the Sikhs who had abandoned the city of Anandpur and its forts only to be attacked. Guru Gobind Singh fought a successful battle at Muktsar and then moved towards Talwandi Sabo.
