With utmost speed they made their way back through the woods, and told Commander Monro what they had seen.

As Seth rightly judged, the brave old man, while fully realizing the seriousness of the situation, did not for a moment contemplate the evacuation of the fort, or the anticipating of the attack by sending a message of surrender to Montcalm.

What he did do was at once to despatch a note to General Webb, who was at Fort Edward, fourteen miles distant, with nearly two thousand men, informing him of the advance of the French and asking for reinforcements, a request which he repeated again and again during the siege, without evoking any response from Webb, who seemed to have been too timid to do as he should have done, namely, hasten forward with his troops to the support of his imperilled brethren in arms.

All told, including sailors and mechanics, Monro had a bare two thousand men wherewith to oppose the eight thousand of the French commander. Yet when Montcalm, having arrived within striking distance of the fort, and completed his preparations for the siege, sent an aide-de-camp to him with the following letter:

"I owe it to humanity to summon you to surrender. At present I can restrain the savages, as I might not have power to do under other circumstances, and an obstinate defence on your part can only retard the capture of the place a few days, and endanger an unfortunate garrison which cannot be relieved. I demand a decisive answer in an hour;" the doughty Scotchman gave his answer at once, and it was that he and his soldiers would defend themselves to the last, emphasizing his refusal by a broadside from his cannon so soon as the truce was ended.

While the white flags were flying the Indians swarmed over the fields before the fort; and when they learned the result of the parley, an Abenakis chief shouted exultantly in broken French:

"You won't surrender, eh! Fire away then, and fight your best, for if I catch you, you shall get no quarter"—a threat that was only too awfully fulfilled in the sequel.

At this time Fort William Henry was an irregular bastioned square, formed by embankments of gravel, surmounted by a rampart of heavy logs laid in tiers crossed one upon another, the interstices being filled with earth. The lake protected it on the north, the marsh on the east, and ditches with chevaux-de-frise on the south and west. Seventeen cannons, great and small, besides mortars and swivels were mounted upon the ramparts.

Montcalm's first proceeding was to open trenches for the protection of his soldiers—a task of extreme difficulty, as the ground was covered with half burned stumps, roots, and fallen trunks. All night of the 4th of August eight hundred men toiled with pick and spade and axe, while the cannon from the fort flashed through the darkness, and grape and round shot whistled and screamed over their heads.

Before daybreak the first parallel was completed, and a battery nearly finished on the left, while another was well started on the right. The men now worked under cover, safe in their burrows, one gang relieving another, as the operations went steadily on all day.
