The presence of so many people must have necessitated a dining hall, a communal kitchen, sanitary facilities at Pilgassi Acres. Those structures had not survived except as barren patches among the weeds. Dig down a little—Percy had learned this technique in his research—and you would find a layer of charcoal for each burned building or outhouse. Not every structure in Pilgassi Acres had survived the years, but each had left its subtle mark.

One of the five barns was not like the others, and I made this observation to Percy Camber as soon as I noticed it. “The rest of these barracks, the doors and windows are open to the breeze. The far one in the north quarter has been boarded up—d’you see?”

“That’s the one we should inspect next, then,” Percy said.

We were on our way there when the first bullet struck.

My mother had always been an embarrassment to me, with her faded enthusiasms, her Bible verses and Congregationalist poetry, her missionary zeal on behalf of people whose lives were so tangential to mine that I could barely imagine them.

She didn’t like it when I volunteered for Cuba in 1880. It wasn’t a proper war, she said. She said it was yet another concession to the South, to the aristocracy’s greed for expansion toward the equator. “A war engineered at the Virginia Military Institute,” she called it, “fought for no good reason.”

But it blended Northerners and Southerners on a neutral field of battle, where we were all just American soldiers. It was the glue that repaired many ancient sectional rifts. Out of it emerged great leaders, like old Robert E. Lee, who transcended regional loyalties (though when he spoke of “America,” I often suspected he used the word as a synonym for “Virginia”), and his son, also a talented commander. In Cuba we all wore a common uniform, and we all learned, rich and poor, North and South, to duck the Spaniards’ bullets.

The bullet hit a shed wall just above Percy Camber’s skull. Splinters flew through the air like a cloud of mosquitoes. The sound of the gunshot arrived a split second later, damped by the humid afternoon to a harmless-sounding pop. The rifleman was some distance away. But he was accurate.
