Boot fall, echoing down the corridor, ended the debate. The security guard ran through the double doors, his arms pumping, his shirt-tail flapping behind him. “They’re here,” he called. He ran right past Sonja and out the back door, announcing his immediate resignation in a breathless shout.

“Who?” Sonja called after him. “Feds or rebels?” No answer. Xenia held an ice cube in her mouth, afraid to break it. No one spoke. The shuffle of military boots paused at the closed double doors. The air was stretched so taut Natasha could have walked across it. A sharp kick, initially mistaken for a gunshot, jolted them all and flung open the double doors. Four bearded men entered with machine guns raised.

“I retired seven years ago,” Deshi said to no one in particular.

“We hereby liberate this hospital for patriotic use for the glorious campaign for national independence,” the shortest rebel declared. Dirt powdered his cheeks. Blood stained his shirt and trousers. He glared at the room, daring them to blink. “Who’s in charge?”

Across the room, with an exasperated roll of her eyes, Sonja raised her hand.

“I am the field commander of the fourth brigade of the National Military of the Chechen Republic of Ichkeria,” the shortest rebel said. He lowered his gun and took small, plodding steps to Sonja. “There are forty of us. Most need medical attention. Everyone needs food and water.”

“We could amputate all their legs,” Maali suggested, but the limping entrance of thirty-six more rebels made permission a formality. Sonja agreed to treat the wounded provided they removed their boots. They corralled the rebels in one of the ghost wards, sharing an unspoken consensus that the quicker the work was done, the better for all involved. The rebels asked for treatment by ascending order of rank, rather than by triage. The lower ranks were first into battle, the commander explained in a clipped northern accent, and thus had suffered the longest. Natasha’s throat tightened as she cut through the trouser leg of a curly-haired private. Nothing but pale down on his cheeks and pink clouds in his eyes. She hadn’t touched a man’s trousers in five and a quarter years.

“What are you doing?” he asked, supine on the hospital bed.

“Giving you shorts. You have lovely legs.”

“Where are my legs?”

“Still here. Don’t worry.”

She tried to be gentle, but shrapnel had cratered his left calf. “Hold on,” she said. “Just hold on.” Her sweat-slickened bangs stuck to her forehead. She wanted to ask his name, but what if he died and she was left here with his name? The name Natasha wouldn’t learn was Said. He came from a Grozny suburb, where his mother, a veterinary’s assistant, brought home the litters abandoned on the clinic doorstep. The war had already taken his mother, but he would live to return home to her cats, which had multiplied to the population of a village during the war years, feasting, as they did, on the burgeoning estate of rats and mice. Working odd jobs and sacrificing the comforts of wife and family, he would spend his life caring for the descendants of his mother’s cats. Eight hundred and eighty-two, all named for his mother, though he would never know that exact figure. In sixty-six years, on his deathbed, he would remember that distant afternoon, when the fingers of a beautiful nurse had mined metal from his legs. He would remember it as the moment of greatest intimacy he ever had had with a woman. Then he would remember his cats.

Natasha called to Sonja, asking for pain relief. The young man was incoherent, addressing his mother in a jar of cotton swabs. Across the room, the surgical saw paused, but Sonja didn’t look up from the half-severed arm. “You’ll have to get it yourself,” she said calmly. Given her history with the drug, Natasha never prepared or administered the heroin. Dreams of bent spoon handles persisted, and five years clean she was still afraid a cigarette lighter could reheat her cravings. But she peeled off the latex gloves and jogged to the canteen. Now wasn’t the time for caution, not with that boy on her hospital bed. In the cupboard, behind an armory of evaporated milk, she found it. It compacted in her grip, filling the corners of the plastic bag. Alu’s brother had claimed there wasn’t enough talc in the bag to powder a baby’s bottom. The Italian junk Sergey had shot into her had contained enough to service a nursery, and even that had laid electric lines where her veins had been. But this? Ninety-eight percent pure? She spat in the sink; she was salivating. You can control your reactions. You can control your reactions, she repeated. It took two minutes to cook. She only had to take one syringe to the trauma ward, but for the twenty-meter walk, when she was alone with it, she felt vastly outnumbered.

When it came time to treat the commanding officers, the last packets of surgical thread had already disappeared into the limbs of their subordinates. The field commander, the last to receive medical attention, lay on Sonja’s cot. The blood of his command soaked the sheets, and when his bare shoulders touched it, he sighed. Between his beard and his eyes, a slim band of soil-colored skin suggested many months of sunshine and malnutrition. Natasha watched while her sister treated him. A long, semicircular gash split his left pectoral. “My chest is grinning at me,” he observed.

Sonja flooded the wound with saline and iodine. With forceps she pinched through the gash for shrapnel fragments. It had begun to clot, but wouldn’t heal without stitches. The rebels looked on with reverent interest.

“We have a problem,” Sonja said. The commander nodded to the ceiling. “We need to get you stitched up, but we’re out of surgical thread. We simply don’t have the supplies on hand to treat so many field injuries.”

“He can have mine,” murmured a thin man, whose beard was half shaven to accommodate thirteen stitches on his left cheek. A chorus of offers followed. Even those without a single stitch vociferously pledged their surgical thread.

“It isn’t sanitary,” Sonja said with a finality that ended debate. None appeared too disappointed that his offer was declined. “Don’t you have field medical kits? Anything we can sterilize and sew into you?”

A junior officer appeared with a small green bag. Natasha sifted through it while Sonja held a compress to the wound. She pulled out a pink toothbrush with a fan of gray bristles, a small bottle of nonalcoholic mouthwash, a tube of fluoride whitening paste, five tubes of toothpaste, on which the five daily prayers were written in black marker, and three rolls of unwaxed dental floss.

“The floss,” Sonja said. “It might work.”

The field commander grimaced as the alcohol-wetted floss followed the needle through his skin. He refused the offer of pain relief. Natasha admired his abstinence.

“Have dentists begun enlisting?” she asked as Sonja slipped the needle in a fifth time. If he refused anesthetic, she could at least offer the distraction of conversation.

“No, it was a captain’s private supply.”

“Did he have fine teeth?”

“Yes,” the field commander said. His open mouth revealed a more relaxed philosophy toward dental hygiene. “They were beautiful, beautiful things. He brushed five times a day, always before prayer, as if performing an ablution on his mouth.”

“Was he conscious of his health in general?”

“Not really. He smoked no fewer than two packs a day.”

“He sounds like a strange man.”

“You get that way. In the first war I fought with a man who went through a roll of antacids every day.”

“That can cause an electrolyte disturbance: hypercalcemia. Stones, bones, moans, groans, thrones, and psychiatric overtones. That’s the mnemonic,” Natasha said, and repeated psychiatric overtones to herself. She wondered if Maali had a taste for antacids.

“I doubt it matters. He’s very dead now. Besides, we ate nothing but buckwheat kasha. No, he took antacids as a calcium supplement. He was terrified of osteoporosis.”
