I dig out a piece of information today.,
"In Kohat where the Khattak chiefship of Teri, we are told, " was but little affected by the Sikh conquest" and the Teri chief "at annexation was continued in the management of the whole Teri tahsil ".
Census of India, 1911 .. (1912)p.65
In 1836, however, Ranjit Singh became reconciled to Sultan Muhammad, and restored to him in service jagir Hastnagdar and half Doaba with Kohat, Teri and Hangu, the annual revenues of which were Rs. 1,50,000. At the same time Rasul Khan, the Khattak chief, excited disturbances and the Sikh garrison, which was retiring from Teri, were massacred on the road near Jatta. Harri Singh Nalwa was killed in 1837 in a battle near Jamrud. Tej Singh administered the Peshawar Government for a short time in his place until relieved by General Avitabile, who retained charge for five years from 1838 to 1842, and was again followed by Tej Singh, who governed for four years. In 1846 Tej Singh was succeeded by Sher Singh, who was accompanied by Colonel George Lawrence as assistant to the newly appointed British Resident at Lahore. All this time Sultan Muhammad remained jagirdar and ruler of Kohat.

The Sikhs, on occupying the country, found themselves unable tolevy revenue from the mountaineers. Ranjit Singh placed Sultan Muhammad Khan in a position of importance at Peshawar, and made him a grant of Kohat, Hangu, and Teri. One Rasul Khan became chief of Teri, and on his death in 1843 was succeeded by his adopted son, Khwaja Muhammad Khan. Meanwhile, Sultan Muhammad Khancontinued to govern the rest of the District through his sons, though the country was generally in a disturbed state, and the upper Miranzai villages were practically independent. When the Sikh troops took up arms at Peshawar on the outbreak of the second Sikh War, George Lawrence, the British officer there, took refuge at Kohat ; but Sultan Muhammad Khan played him false, and delivered him over as a prisoner to the Sikhs.

So an entire Sikh garrison was destroyed by Khattaks of Teri (modern day Karak district) in 1836 while they were leaving it, thats the event one year before death of hari Singh nalwa. Now Miranzai, Teri , kohat are very close to Peshawer where Hari singh was stationed. Here is the map of location of kohat, it is adjacent to Peshawer,
It is clear that Hari singh failed to subdue the troublesome Pashtun tribes around Peshawer and adjacent districts, there was no writ of Sikh rule beyond peshawer city. The jamrud fort adventurism is beyond my understanding when they didnt have a proper control over the already occupied areas.
