His surmise proved correct. The holder of the fort was taken at a disadvantage; he fired wildly in consequence, and had the mortification of perceiving that not one of his shots took effect.

The attacking party, of whom Hal was not one, reserved their fire, and seemed bent upon coming to close quarters. Grimly determined to make it warm for them when they did close with him, the defender sprang on to the roof, and, regardless of the fact that he was exposing himself recklessly, took up his stand by the flagstaff, and, throwing down his catapult, whirled his lasso wildly round his head.

On came the attacking party; he faced them, and with a coolness that did him credit at such a critical moment he picked out the one that he could most easily capture, and was in the act of hurling the lasso, when, up from the very midst of the hawthorn bushes at the back of the fort, Hal's voice was heard again.

"Three!" he shouted: and turning like lightning to meet this fresh foe, who he guessed would prove the most formidable, the boy saw an immense jet of water spurt high into the air. Twenty feet it rose, and then descended full and fair upon his head. A mingled shout of defiance and joy told Hal that his aim had been good, and he continued to ply the hose. At the same moment eight cannon-balls, five at least of which hit him, were thrown at the harassed defender, whose helmet was now full of sand and water.

Choking and gasping and almost unable to see, so great was the force with which the stream was playing upon his face, the boy grasped the flag, determined not to surrender.

But the enemy now surrounded the fort on all sides, and were already scaling the walls. Both Jim and Drusie were anxious to gain the glory of capturing the flag, and a desperate fight raged round the flagstaff. Twice Drusie laid hands upon it, and twice she was driven back.

The hose played upon besieged and besiegers alike, and all the combatants were being drenched to the skin. But the battle continued to rage, and, though he was hampered by his helmet and sorely outnumbered, the valour displayed by the holder of the fort might yet have gained him the day, if Jim, warned by a cry from Hal that the water in the barrel was giving out, had not succeeded in grasping the flagstaff.

"Jump with it, Jim, jump!" Drusie cried, and flung herself between them. But with one hand the boy tossed her aside, while with the other he clutched at the flag.

There was a short tug of war; then a sharp sound of tearing cloth; and while the gallant defender toppled backwards into the stream, carrying the greater part of the flag with him, Jim fell down on the other side, bearing with him the flagstaff and the fluttering remnant of the Union Jack.

Both sides would certainly have claimed the victory, for both held a portion of the flag, had not Drusie, scrambling out of the hawthorn bushes into which she had been tossed, jumped into the middle of the stream, and snatched the part that he still held out of the hand of the prostrate, half-drowned enemy.
