The first breast-work was to be built at the narrow end of the plateau farthest from the gun-pit.
It commanded the crest of the hill over which the little party had made its final rush, and the path they had followed ran along this ridge, dipping down for two hundred yards, and then rising steeply to the bush-covered knoll, on top of which they had extended and fixed bayonets.
One of Sergeant Haig's sentries (Williams's "square leg" man) was already standing in the gap made by the path as it disappeared into the dense bushes, and it was evident that an attacking force could take splendid cover there, and could sweep the greater part of the plateau with rifle fire.
This breast-work was therefore built right across the narrow end of the plateau, sand-bag was piled on sandbag till it was nearly three feet high, and as the men had hauled some great logs of timber across from the gun-pit to strengthen it, they called it eventually the "Log Redoubt", making loopholes in it for their rifles.
The bush-covered knoll in front of them they named "Bush Hill", and few will ever forget it.
Some of the men dragged sand-bags to the edge of the plateau, overlooking the harbour, to form two low breast-works, one on each side of the zig-zag path, as it led up to the gun-pit.
For twenty yards in front of these two breast-works the steep hillside was bare, but below this the whole hill down to the pirate village, which they could see at the bottom gradually becoming distinct as daylight increased, was covered with small trees and dense brushwood, through which the zigzag path wound its way upwards.
Men lying behind these sand-bags were somewhat protected by the Log Redoubt from rifle fire from Bush Hill, so Williams contented himself with raising them only two sand-bags high.
These being roughly completed, more sand-bags were dragged to the opposite end of the plateau, and a little redoubt constructed fifty yards beyond the gun-pit. From here fire could be directed along the farther ridges, which were devoid of cover and sloped steadily downwards, and also down both the harbour and sea slopes of the hill.
Sergeant Haig and nine Blue Marines were given charge of this work, and so it was known as "Haig's Redoubt".
