There were now about a hundred soldiers at the foot of the wall, and the fate of Steens appeared to be sealed, when help came as from the clouds. Throughout the struggle forms had been flitting in the rear of the soldiers. The fog had concealed from the Sheriff that he was fighting, as his predecessor had fought, within a ring of spectators many hundreds in number; and to-day not a few of these spectators had brought guns. It is said that in the hottest of the fray Trevarthen broke out from the rear of Steens and marshalled them. Certain it is that no sooner were the soldiers huddled beneath the wall than a bullet sang down the road from the north, then another, then a volley; and as they faced round in panic on this flanking fire, another volley swept up the road from the south and took them in the rear.

They could see no enemy. Likely enough the enemy could not see them. But, packed as they were, the cross-fire could not fail to be deadly. The men in the courtlage had drawn back towards the house as the ladder began to sway above the wall. They waited, taking aim, but no head showed above the coping. They heard, and wondered at, the firing in the road: then, while still they waited, one by one the ladders were withdrawn.

The soldiers, maddened by the fire, having lost their captain, and being now out of hand, parted into two bodies and rushed, the one up the other down the road, to get at grips with their new assailants. But it is ill chasing an invisible foe, and a gun is easily tossed over a hedge. After pursuing maybe for quarter of a mile they met indeed two or three old men, innocent-looking but flushed about the face, sauntering towards the house with their hands in their pockets; and because their hands when examined were black and smelt of gunpowder, these innocent-looking old men went back in custody to the post where the bugles were sounding the recall. The soldiers turned back sullenly enough, but presently quickened their pace as a yellow glare in the fog gave the summons a new meaning. Their camp was ablaze from end to end!

This was a bitter pill for the Sheriff. He had come in force, determined to prove to the rebels that they had a stronger man than Sir James Tillie to deal with, and he had failed even more ignominiously. He cursed the inhabitants of West Cornwall, and he cursed the fog; but he was not a fool, and he wasted no time in a wild-goose chase over an unknown country where his men could not see twenty yards before them. Having saved what he could of the tents and trodden out the embers, he consulted with the young lieutenant now in command and came to two resolutions: to send to Pendennis Castle for a couple of light six-pounders, and, since these could not arrive until the morrow, to keep the defence well harassed during the remaining hours of daylight, not attempting a second assault in force, but holding his men in shelter and feeling around the position for a weak point.

The day had passed noon before these new dispositions were planned. Posting ten men and a corporal to guard the charred remains of the camp, and two small bodies to patrol the road east and west of the house and to keep a portion of the defence busy in the courtlage, the lieutenant led the remainder of his force through an orchard divided from the south end of the house by a narrow lane, over which a barn abutted. Its high blank wall had been loopholed on both floors and was quite unassailable, but its roof was of thatch. And as he studied it, keeping his men in cover, a happy inspiration occurred to him. He sent back to the camp for an oil-can and a parcel of cotton wadding, and by three o'clock had opened a brisk fire of flaming bullets on the thatch. Within twenty minutes the marksmen had it well ignited. Behind and close above it rose a gable of the house itself, with a solitary window overlooking the ridge, and their hope was that the wind would carry the fire from one building to another.

Thatch well sodden with winter's rain does not blaze or crackle. Dense clouds of smoke went up, and soon small lines of flame were running along the slope of the roof, dying down, and bursting forth anew. By the light of them, through the smoke, the soldiers saw a man at the window above, firing, reloading, and firing again. They sent many a shot at the window; but good aim from their cover was impossible, and the loopholes of the barn itself spat bullets viciously and kept the assault from showing its head.

The man at the window—it was Roger Stephen—exposed himself recklessly even when the fire from the loopholes ceased, as to the lieutenant's surprise it did quite suddenly.

For a minute or so the thatch burned on in silence. Then from within the building came the sound of an axe crashing, stroke on stroke, upon the posts and timbers of the roof. Some madman was bringing down the barn-roof upon him to save the house. The man at the window went on loading and firing.

The soldiers themselves held their breath, and almost let it go in a cheer when, with a rumble and a thunderous roar, the roof sank and collapsed, sending up one furious rush of flame in a column of dust. But as the dust poured down the flame sank with it. The house was saved. They looked about them and saw the light fading out of the sky, and the lieutenant gave the order to return to camp. The man at the window sent a parting shot after them.

And with that ended the great assault, but scarcely had the Sheriff reached camp when a voice came crying after him through the dusk, and, turning, he spied a figure waving a white rag on a stick. The messenger was old Malachi, and he halted at a little distance, but continued to wave his flag vigorously.
