Shortly afterwards William heard the three leaving the house and the car go off in the direction of Dublin. He waited for a few minutes to give the stranger time to get well away, then got out his bicycle, and with his revolver ready in his right hand, started off for Ballybor.

While William was riding for dear life to Ballybor, Sheila and Patrick were tearing across Ireland to fetch the arms for the ambuscade. They reached Dublin without any trouble, had a short rest and a meal, collected the arms from the secret hiding-place, and then started off on the return journey by a different route.

By previous arrangement they were met outside the town after dark by the local Volunteer captain and a party of men, who took over the arms from them, when they drove on home. Owing to the fact that they had left and returned at night, no one in the town had any idea that they had been away.

For some weeks past the police had been bringing tremendous pressure to bear on the rebels throughout the south and west, which pressure corresponded with the appointment of a new Inspector-General of the R.I.C. So strong was the pressure growing that the rebel staff were afraid of a collapse, and when their secret service learnt that the I.G. would be motoring to Ballybor on this particular Wednesday night, they determined to ambush him in Knockbrack Wood, and to kill him at all costs.

Knockbrack Wood lies along both sides of a main road for a distance of about a mile and a half, and in the middle the road makes a sharp bend to avoid a huge granite rock which towers above the trees and makes this corner quite blind. On the far side of this bend from the direction of Ballybor the road rises suddenly, so that a car going towards that place would be likely to approach the bend at a good pace, and be unable to avoid an obstacle or trench just round the corner.

Here it was settled to make the attempt on the I.G.’s life, and on the Wednesday the local Volunteers, under the direction of staff officers from Dublin, started to make the preparations. By dark all was complete, except to cut a trench across the road, and a large party of Volunteers had taken up positions on each side of the road at the bend.

It was expected that the I.G.’s car would be wrecked, or at any rate brought to a standstill, just beneath the big rock, on the top of which there was a bombing post, with orders to drop a flare as soon as the car was below, to enable the riflemen to aim in the dark, and to follow up the flare with a shower of bombs.

Patrick and Sheila waited until it was nearly dark, when they motored to Knockbrack Wood, leaving the car up a narrow lane in the wood, about a hundred yards from the big rock on the Ballybor side. They then retired to a safe distance to await events.

After several hours of waiting they left the wood and walked up and down the road to Ballybor, as by this time they were half frozen with cold. Shortly afterwards they were joined by the Volunteer captain, and as it would soon be daylight, Patrick suggested to him that the men should be sent home.

The Volunteer captain was a stupid fellow, and further, he resented any suggestion as to what he should do from Patrick; and the three of them—Sheila, Patrick, and the captain—began a heated argument in the middle of the road: the captain argued that an order was an order, and that he would keep his men there until the next night if necessary, or even longer.
