When the fighting at the gap became close, Burnet seized the rifle of a fallen Arab and did strenuous work in holding the enemy at bay. Such of them as succeeded in clambering upon the parapet were hurled back upon their comrades in the kelaks beneath. But the assailants were all sturdy Turks and stern fighters. Fresh men were continually pouring across the gap, and the Arabs, fight as gallantly as they might, would sooner or later yield to the enemy from sheer weariness. The breastwork could not be held much longer. Indeed, the inevitable moment came earlier than Burnet expected, for two kelaks, propelled by stout polemen, pushed beyond the gap, and ran close in on the side of the causeway, the Turks upon them opening fire upon the defenders from the flank and rear.
Burnet's little band was thrown into momentary confusion by this unexpected attack, and several Turks gained a footing on the breastwork. A final effort was necessary before the position could be safely abandoned. Telling off a number of the men to return the fire from the kelaks, Burnet called on the rest to support him. With a shrill cry they rallied, and threw themselves upon the enemy with an impetuosity that nothing could withstand. The Turks were forced back, some falling upon the kelaks in the gap, others into the water. Once more the breastwork was clear.
Then Burnet gave the order for retirement. The flank attack had been beaten off; the causeway was open. One by one at intervals of a few yards the Arabs dashed back towards the shore. Burnet kept a few men with him to act as rearguard, and waited until the wounded had almost reached the end of the causeway before he followed them up. It seemed that the enemy was hardly aware of what was happening, for the retirement was not harassed until the last few men had almost reached the bridgehead. Then, however, the fusillade broke out again, answered by the Arabs on shore, and one or two men, including Burnet himself, were hit before they had gained shelter. Burnet had already seen that the kelaks which had headed for the shore had been driven back, in spite of the support of the machine-guns. The Arabs at the bridgehead and in the redoubts had suffered very little loss, and he felt that the honours of this first encounter were with the defence. The Turks, seeing that their opponents had made good their retreat, ceased fire. They had captured the gap, but it was clear that they had to master a further line of defences before they gained access to the island. What would be their next move? Their success at the gap might give them sufficient encouragement to push on after a breathing space and finish the job while their blood was up and the tide seemed to have turned in their favour. It might prove a somewhat desperate undertaking unless they had more artillery at their disposal than the two machine-guns which had already been in action; but they in their turn would not suspect that they had to face machine-guns, and they would probably conclude that the Arabs' retirement after a short action was an earnest of further retreat as soon as they were hard pressed.
It seemed to Burnet that a serious attack in force along the causeway was to be expected and provided against. Like many another subaltern in the heroic annals of British warfare, he found himself alone, at the head of an alien force, badly provided, and, what was worse, totally inexperienced. But it is in such circumstances as these that British valour has shone forth most brightly, and British ingenuity most thoroughly proved itself, and Burnet was to show forth those sterling qualities which hundreds before him had evinced.
If the defence was to have the least chance of success, the rough and hastily contrived fort at the bridgehead must be held to the last moment. In spite of the limited quantity of ammunition, the time had clearly come to bring the machine-guns into action. Burnet sent for the two gunners, who had been itching to take their part, and told them frankly what he expected, and how he proposed to meet the attack.
"We'll give 'em what for, sir," exclaimed Sturge, rubbing his hands. "With Bill on one side and me on the other we'll keep that Margate pier clear of Turks for a hundred years."
"Well, you know how many rounds you have," said Burnet. "But I don't want both guns in action at first. Both might be knocked out. We'll keep one in reserve, in case anything happens. The one we have in the fort is certainly pretty well protected against anything less than a 9-pounder, but we must provide against accidents. You can help each other in working it. Open fire only if the enemy make a rush along the causeway."
Something more than two hours passed. The enemy were seen to be framing a practicable floating bridge from the kelaks, and Burnet ordered some of his best marksmen to snipe them. But they were to some extent covered by the captured outwork, and completed their task with very little loss.
A few minutes afterwards, the kelaks which had not been required for the bridge emerged from both sides of the gap and approached the island, keeping close to the walls of the causeway. At the same time a column of Turks streamed across the bridge, sprang over the abandoned outwork, and rushed without making any attempt at regular formation straight for the bridgehead. From the shelter of their walls on the causeway itself, as well as from their main position at the further end, the enemy opened a heavy covering fire, to which the Arabs replied thinly, and chiefly for form's sake, Burnet desiring to mislead the Turks while husbanding his ammunition.
The head of the enemy column had advanced a hundred yards along the causeway before any attempt was made to check them. Then, however, while they were in full career, the machine-gun suddenly rapped out its deadly message. The effect was like that of a huge scythe sweeping along the causeway. Within less than a minute there was scarcely a man left erect between the bridgehead and the gap. The few who had escaped the hail of bullets flung themselves frantically into the water, and swam for safety, some of them falling victims to rifle fire from the flanks of the Arabs strung out behind their breastwork near the shore.
