The letter came on a Tuesday, and though I did not see it delivered, I was in the back garden that afternoon, trying without much success to teach Rosie to sit upright on the low wall. I have heard the story of its arrival often enough since that I can picture it nearly as well as if I had watched it myself: a boy on a bicycle, not lingering, as if he understood even at his young age that some envelopes carried more weight than paper ought to hold. He had delivered a dozen such letters that same week to houses up and down our street, Mother told me, and had grown, in the process, rather too accustomed to the particular hush that fell over a doorway the moment such an envelope changed hands.
Mother read it standing in the hallway with her coat still on, fresh from the factory and smelling faintly of machine oil, and though she had known it was coming, though she had spent the better part of a week readying herself for exactly this letter, her hands still trembled as she folded it back along its creases. She told me, long afterward, of the particular fury that rose in her at one line of it; a brisk, official reminder that parents were asked to say their goodbyes promptly and without undue delay, as several hundred children would be passing through the station that same morning and the schedule allowed little room for lingering farewells. As though a mother's goodbye to her only child could be scheduled and rationed like everything else the war had touched, she said. She read that line three times before she could bring herself to fold the letter away and come and find me.
I was to report to the railway station the following Thursday morning, with a tag pinned to my coat, my gas mask in its box, and one small case of belongings, no more than I could carry myself, for there would be no one to carry it for me once the train began to move.
That Wednesday evening, Mother and I sat together on my bedroom floor with the little brown suitcase open between us like a small, patient mouth waiting to be fed. I remember the negotiating over what should go inside it, for I held firm opinions in those days about a great many things; about the placement of my hair ribbons, about the proper way to eat a boiled egg, which I insisted must always be approached top-first, with a small salute of the spoon before the shell was cracked, and Mother, bless her, indulged most of them even on so difficult an evening.
"What shall we bring?" she asked, though she already knew the answer would take some negotiating, as it always did with me.
"Rosie," I said at once, holding up my doll, and there was never any real question of leaving her behind. In she went, along with a warm plum-colored sweater Mother had knitted the winter before, only just growing snug across my shoulders, because the north would be colder than London come winter, and there was no telling, that first year, whether Mother might manage to send a replacement in time. Then went my favorite storybook, its spine cracked from a hundred bedtime readings, filled with pictures of foxes in waistcoats and rabbits who wore spectacles. Then the family photograph, wrapped carefully in a handkerchief so the little frame's glass would not crack against the journey, tucked in beside a spare pair of stockings and my second-best cardigan.
"What about my drawing things?" I asked, holding up my tin of colored pencils, worn down to stubs from enthusiastic use.
"There's just room, I think," Mother said, tucking the tin into a corner, "if we're clever about it."
I did not see, that evening, the last thing Mother tucked into the case, which was a handkerchief she had embroidered herself in the early days of her marriage, white linen with a small blue forget-me-not stitched into one corner, the kind of thing meant for special occasions rather than the everyday business of a nose. She told me, long afterward, that she had stitched it during the long, quiet evenings of her honeymoon, when Father had gone out fishing with her own father and she had sat on the cottage porch with her needle and thread, imagining all the happy years that lay ahead of her. She folded it in beneath the sweater in secret, where I would not find it until I needed it, hoping without quite being able to say so aloud that her love might find its way to me exactly when I needed it most, even across whatever distance the war might put between us. I have that handkerchief still, in a wooden box on my windowsill, and I think of that secret kindness every single time I look at it.
"There," Mother said, closing the case and fastening its brass clasps. "That's everything a brave girl needs."
"It isn't very big," I said, looking at it.
"No. But it's amazing how much a small case can hold, if you pack it with the right things."
I went to bed not long after, and I did not see Mother sit up alone at the kitchen table with a cup of tea gone cold beside her, turning over in her mind whether she had made the right choice. I did not see her weep, quietly, into the small hours, or hear her resolve to write to Father the very next morning so that wherever the post found him, he might picture me safe among green hills rather than beneath a London sky grown dangerous with bombers. She told me of that night many years later, when I was a grown woman myself and could finally understand the particular loneliness of the decision she had carried alone; how she thought of her own mother, long since taken by influenza, and wondered whether she would have made the same choice in her place, and decided, staring at the tea leaves settling in the bottom of the cold cup, that she would have, because there was no other choice a mother who loved her child could sensibly make, not with a crater sitting where cabbages had grown only a fortnight before.
Thursday morning came gray and reluctant, as though London itself did not wish to let the day begin. Mother dressed me in my good wool coat, buttoned to the throat though the September air was mild, because it seemed important to her, she told me later, that I look properly cared for when I stepped off into the world alone knowing that whatever family received me at the other end of the journey should see, in the neatness of my coat and the careful plait of my hair, evidence of a mother's love, even from a distance. She pinned the evacuation tag to my lapel, CHARLOTTE SPENCER, in careful block letters, and hung my gas mask box on its string across my chest, where it sat like an ungainly medal.
I chattered the whole walk to the station, I am told, asking questions about the countryside and about sheep and about whether the family I was going to would have a dog, and if so what sort, and Mother answered every one of them, grateful, she told me later, for the distraction of it, because it meant she did not have to think, even for a moment, about what waited at the end of the walk.
The station itself I remember more clearly than almost anything else from that whole year; the sheer size of the crowd, thousands of children clustered in their good coats and paper tags, some clutching siblings' hands, some standing entirely alone, small islands of fear in a sea of strangers, teachers with clipboards calling names in voices gone hoarse, wardens herding us this way and that, and everywhere, everywhere, parents with handkerchiefs pressed to their mouths, fighting a battle most of them were losing. The whole platform seemed to me, even at four years old, to be filled with a low, terrible murmur of barely suppressed grief.
A young teacher checked my name against her list, running a gloved finger down the page until she found it. "Spencer, Charlotte. That's right, dear. You'll be on the ten o'clock, platform four. There's a good while yet before she boards, if you'd like the time."
Mother knelt down in front of me one last time and buttoned my coat again, though it did not need buttoning, simply, I understood only much later, because her hands needed something to do that was not shaking.
"You're my whole world, sweetheart," she said, taking my face in her hands, memorizing, she told me afterward, every detail of it; the small scar above my left eyebrow from a tumble off the garden wall two summers before, the particular way my nose wrinkled when I was trying not to cry. "Do you understand that? My whole world. Be brave for Mummy until I can come and see you. Can you do that for me?"
I nodded, though my lip had begun to tremble.
"I'll write every week," she said. "I promise you that. Every single week, no matter what happens, no matter how tired I am from the factory or how bad the raids get. Will you promise me the same?"
"I promise," I whispered.
An elderly neighbor, Mrs. Ellery, who had known me since my christening and had minded me of an afternoon more than once when Mother's factory shifts ran long, pressed through the crowd to tuck a twist of barley sugar into my coat pocket. "For the journey, poppet," she said, her own eyes brimming behind her spectacles. "You mind your mother's words now, and come back to us safe and sound, do you hear?"
Then the whistle sounded, and the teacher's hand came to rest on my shoulder, and I felt the whole terrible reality of it arrive at once, all my bravery of the past two days cracking open like an egg.
"Mummy!" I cried. "Mummy, come with me!"
"I can't, my darling, I can't," she called after me, her own composure shattering at last, "but I'll see you soon, I promise, I promise!"
I remember being carried forward by the crowd, up the steps and into a carriage already full of other frightened children, their faces pressed to the glass in various stages of the same grief, and I remember pressing my hand flat against the glass as the train began, at last, to move. Mother told me afterward that she ran alongside the train the whole length of the platform, her good shoes slapping against the stones, calling that she loved me, that I should be brave, until the platform simply ran out beneath her feet and she stood at its very edge, waving, long after there was any possibility I could still see her, long after the other parents around her had begun, one by one, to turn away and make their own slow, heartbroken way back toward whatever remained of their ordinary Thursday.
I did not stop waving either, not until the station had vanished around a bend, and London; the crater, the sirens, my empty-chaired supper table, and my mother, my mother, my mother; had disappeared entirely from view, swallowed up behind a curve of track and a stand of blackened trees, leaving nothing behind but the steady rhythm of the wheels and a carriage full of children just as frightened, just as alone, as I was.
I have wondered, many times across the years since, what it must have cost my mother to walk back alone from that platform, through streets that had, only that morning, still held her daughter within them. She never told me much of that particular walk home, though she told me a great deal else about that year, and I have always suspected the silence was its own kind of answer that some griefs are simply too large to be properly described, even to the very child who caused them, however unwittingly, by the simple fact of needing to be kept safe. I know only that she went home to an empty house that afternoon, and that she wrote to me that very evening, as she had promised, the first of what would become, across the following five years, several hundred letters; enough, she told me once with a small, rueful laugh, to paper the whole of our front parlor twice over, had she ever been foolish enough to try.
I did not understand, at four years old, the full weight of the promise I had made her on that platform; to be brave until she could come to me. I understand it now, having spent a lifetime turning that morning over in my mind, as the first of many promises I would try, imperfectly but with my whole heart, to keep across the five long years that followed.
Mrs. Ellery's barley sugar, I might add, lasted precisely as far as the outskirts of London, dissolved to nothing by the time the fields began, but I have never forgotten the particular kindness of a woman who was not my mother pressing sweets into my pocket simply because she could think of nothing else to give a frightened child on her way into the unknown. I have tried, across my own long life, to be that kind of woman to other people's frightened children, when the occasion presented itself, in whatever small way I could manage, a lesson I did not know I was learning that morning on the platform, but which I carried forward all the same, the way one carries forward so much of what kindness teaches without ever quite noticing the lesson at the time it is given.
I think, too, of the particular strangeness of that walk home from the station for anyone who witnessed it; the quiet emptiness of streets that had, only an hour before, rung with the noise of thousands of parents and children saying their goodbyes, the way an ordinary Thursday simply resumed itself around all that grief, buses running, shops opening, the whole indifferent machinery of the city carrying on exactly as it had the day before, as though nothing at all irreplaceable had just been carried away on a northbound train. Mother told me once that she found that ordinariness, on the walk home, almost harder to bear than the goodbye itself; that some part of her had wanted the whole city to stop and mark what had happened, and instead found it simply going on, the way cities do, indifferent to any single family's sorrow, however large it loomed within that family's own four walls.
