Chavasse hit the ground heavily perhaps a hundred yards from the bridge. He lay there for a moment, winded, then stood up and struggled out of his parachute harness. There was still no sign of the Chinese and he unslung the Sten gun and ran along the uneven track between outcrops of rock.

It was stupid, of course, such exertion of that altitude, and by the time he reached the bridge he was gasping for air, his breath like white smoke. He started across and it swayed gently. He got to the centre, took off the haversack and selected a block of plastique, inserted a five-minute timer, lay down and reached over the edge and wedged the explosive into a space between the ends of two struts. He activated the timer and stood up, and at that moment a Chinese jeep appeared on top of the rise on the other side.

Its machine gun opened up at once. Chavasse ran, the Sten gun in one hand, the haversack in the other. He reached the end of the bridge, ducked behind one of the supporting posts, found another block of plastique, inserted a yellow two-minute fuse and activated it.

The jeep kept firing, bullets clipping wood from the post. He laid the plastique block down and returned fire with his Sten, and a lucky shot knocked one soldier out. The jeep, halfway across the bridge, paused, with another just behind it, and on the ridge above the rest of the column arrived.

“Just stay there,” Chavasse prayed, and tossed the block of plastique out onto the bridge.

To his horror, it actually bounced over the edge, where it exploded in space. Firing relentlessly, the jeep started forward, followed by the other, and the column moved down on the other side.

Chavasse ran up amongst the rocks, head down, glancing back to see the two jeeps reach firm ground. At that moment and just as the convoy started across, there was a huge explosion. The centre of the bridge twisted up into the air, lengths of timber flying everywhere. The two lead jeeps in the convoy on the other side went with it.
