In the Samarian hills, overlooking the Plain of Sharon, four men stood quietly in the predawn darkness. Below them, spread out on the plain, they could see the straight lights of Lod International Airport almost nine kilometers in the distance. Beyond Lod were the hazy lights of Tel Aviv and Herzlya, and beyond that, the Mediterranean Sea reflected the light of the setting moon.

They stood on a spot that, until the Six Day War, had been Jordanian territory. In 1967, it had been a strategic spot, situated as it was almost half a kilometer above the Plain of Sharon on a bulge in the 1948 truce line that poked into Israel. There had been no Jordanian position closer to Lod Airport in 1967. From this spot, Jordanian artillery and mortars had fired a few rounds at the airport before Israeli warplanes had silenced them. The Arab Legion had abandoned the position, as they had abandoned everything on the West Bank of the Jordan. Now this forward position had no apparent military significance. It was deep inside Israeli territory. Gone were the bunkers that had faced each other across no man's land and gone were the miles of barbed wire that had separated them. More importantly, gone too were the Israeli border patrols.

But in 1967 the Arab Legion had left behind some of its ordnance and some of its personnel. The ordnance was three 120mm mortars with rounds, and the personnel were these four Palestinians, once members of the Palestinian Auxiliary Corps attached to the Arab Legion. They were young men then, left behind and told to wait for orders. It was an old stratagem, leaving stay-behinds and equipment. Every modern army in retreat had done it in the hopes that those agents-in-place would serve some useful function if and when the retreating army took the offensive again.

The four Palestinians were natives of the nearby Israeli-occupied village of Budris, and they had gone about their normal, peaceful lives for the last dozen years. In truth, they had forgotten about the mortars and the rounds until a message had reminded them of their pledge taken so long ago. The message had come out of the darkness like the recurrence of a long-forgotten nightmare. They feigned surprise that such a message should come on the very eve of the Peace Conference, but actually they knew that it would come precisely for that reason. The men who controlled their lives from so great a distance did not want this peace. And there was no way to avoid the order to action. They were trapped in the shadowy army as surely as if they were in uniform standing in a parade line.

The men knelt among the stand of Jerusalem pines and dug into the soft, dusty soil with their hands. They came upon a large plastic bag. Inside the bag were a dozen 120mm mortar rounds packed in cardboard canisters. They pushed some sand and pine needles over the bag again and sat back against the trees. The birds began to sing as the sky lightened.

One of the Palestinians, Sabah Khabbani, got up and walked to the crest of the hill and looked down across the plain. With a little luck -- and an easterly wind sent by Allah -- they should be able to reach the airport. They should be able to send those six high-explosive and six phosphorus rounds crashing into the main terminal and the aircraft parking ramp.

As if in answer to this thought, Khabbani's kheffiyah suddenly billowed around his face as a hot blast of wind struck his back. The Jerusalem pines swayed and released their resinous scent. The Hamseen had arrived.
