...Saragarhi, whose garrison of twenty men fought till death against a horde of six thousand Orakzais mountain tribesmen.
The tribals later admitted to a figure of 180 dead and many more wounded. Some of the details of the closing phases of the fight were pieced together from, the heliograph messages, what could be seen from fort Lockhart and the tribals.
When day broke on the 12th, the Orakzai-Afridi "lashkar" was seen to be in force near Gogra on the east, at the Samana Suk on the west, and round the Saragarhi post, thus severing Gulistan from Fort Lockhart.(Their total number has been variously estimated at from twelve to twenty thousand.)It was, therefore, no longer possible for Colonel Haughton to carry aid to Saragarhi or Guhstan, as he had done twice before. The enemy turned the brunt of their attack on the little post of Saragarhi.
