nine o'clock
The levies were expected to join the next morning . They were to advance with a guide , and turn out the enemy from the top of a dangerous shoot ; from which they would be enabled to hurl down rocks upon the main body , as it advanced . Beynon was to start , at six , to work through the hills to the right rear of the enemy 's position . The main body were to move forward at nine o'clock . Beynon encountered enormous difficulties and , in many places , he and his men had to go on all fours to get along . He succeeded , however , in driving off the enemy ; who occupied a number of sangars on the hills , and who could have greatly harassed the main body by rolling down rocks upon them . The enemy 's principal position consisted of sangars blocking the roads to the river , up to a fan-shaped alluvial piece of ground .
