Letters to Leave Before Deployment: Spouse, Kids, and Homecoming

The five letters to write before you leave, with copyable examples for your wife or husband, your kids, and the day you walk back through the door.

The duffel has been by the door for two days, and everyone in the house walks around it like a sleeping dog. The paperwork is done and filed, down to the budget on the fridge with the pay dates circled. The readiness checklist is complete, and it never once asked you to write a letter to your wife or husband before deployment, or to your kids, or to the people who will be standing in that doorway on the day you walk back through it.

So here is the other half of the packing: not the letters you will send from wherever you are going, which will be wonderful and late and mostly about the food, but the letters you leave behind, written now at your own kitchen table and timed to land while you are away.

Why the Letters You Leave Behind Matter More Than the Ones You Send

Letters from a deployment are a lottery. The connection comes and goes, and the week your daughter turns seven may be the week you cannot get near a screen. The letters you send are made of whatever time is left over. The ones you leave behind are made of the best of you, written before anyone is tired, and each carries something a call cannot: a date.

The National Military Family Association's deployment guide covers the power of attorney, the family care plan, the budget, the will, and last wishes. Letters are not on it. The forms protect your family's affairs. The letters protect their mornings.

The Five Letters Most People Wish They Had Written

  • The letter to your spouse. One page, the real thing.
  • One letter per child. Never one shared between siblings.
  • A letter to your parents. A paragraph is enough.
  • The one sealed letter. The just in case letter, read only if the worst happens.
  • The homecoming letter. Written before you leave, opened when you are back.

The parents letter is the one everyone skips, and it is four sentences of work. Tell them you are all right. Tell them the one thing you got from them that you are taking with you, and be specific, because they will not guess it. Tell them who to call on the week they cannot reach you.

Only one of the five has anything to do with risk. The other four are about a birthday, a bedtime, a Tuesday, and a door opening.

A Letter to Your Wife or Husband Before Deployment

This letter is not a summary of your marriage. It does four small things: it notices something specific about them, it hands something over, it says the thing you keep meaning to say on calls, and it gives permission for the months ahead.

I am writing this at the table with your cup still here from this morning, the one with the chip you refuse to throw out. I wanted you to have something that is not a phone call, because calls are logistics and I keep forgetting the real thing. So here it is.
The real thing is this: I watch you. I watch you do the school run with one shoe on and the toast in your teeth and I think, nobody else could run this place. When people tell you I am the brave one, tell them they have the wrong address. You are doing the hard tour. Mine comes with a schedule and meals.
The thermostat is yours, and I will not say a word when the bill comes. The car makes that noise on the left; ignore it until it makes it on the right. If the dog ends up on the bed, the dog ends up on the bed. I know the rule. I am waiving it.
Here is what I need from you: do not put your life on hold to wait for me. Go to the thing on Fridays. Laugh at something without checking the time difference first. I am coming home to you, and I want to find you there, not a waiting room. You are the best decision I ever made, and I made it on purpose.

That one is a wife writing to a husband. Reverse it and almost nothing changes except the cup. Whichever of you is leaving, the shape holds.

Letters for Your Kids to Open While You Are Deployed, by Age

Two to five. Short, physical, present tense. They hold breakfast and bedtime, not months.

Hello, my favorite person who is four. Are you being a good boss of the dog? I am far away doing my work, and I think about you every single breakfast. Give Daddy a squeeze from me, a big one, and a small one for extra. I love you bigger than the big truck.

Six to ten. A job, a joke, and something to show you when you are back.

Your job while I am gone is the bin on Tuesday nights, which nobody else in that house will remember, and one drawing a week that you do not show me until I am back. Also I heard spelling tests moved to Fridays. Send me the scores. Including the bad ones, of which there will be none.

Eleven to seventeen. Honest, respectful, no assignments and no guilt.

I know this is not a great time for me to be gone. You have your own life and I am asking you to carry a piece of mine. So I will say this once: you do not have to be the adult in the house. Be sixteen. If things get heavy, say so to your dad, or to me when we talk. I am proud of who you are turning into. I have been watching, even when it looked like I was watching the game.

The long letters, for an eighteenth birthday or a wedding, have a guide of their own on milestone letters to your children.

The Tour Calendar: Writing for the Dates You Will Miss

Mark on a calendar the dates you will miss: a birthday, the first day of school, your anniversary, the winter holiday your family keeps, the recital. Write one letter per date and schedule each one for the day itself. Write for the day, not for the absence: a birthday letter is about being nine, not about you being gone.

Happy birthday from very far away. Today you are nine, which means you are finally old enough to know that the cake goes in the oven before the candles go on. Ask your father how I learned that.

The guide to birthday letters for the years you might miss goes deeper, and the post on how to send a message to the future explains how far ahead you can schedule.

Open When Letters Without the Envelopes

You have seen the tradition: a stack of sealed envelopes tucked into a bag before a deployment, each one labeled. Open when you miss me. Open when you need a laugh. Military OneSource's family blog keeps a running list of topics for them, and says, without meaning to, who usually writes them: the person at home prepares a large stack for the person leaving. Nobody tells the person leaving that they can do the same for the people staying.

Paper envelopes fail two ways. Either the whole stack is opened on the first bad night, or the box goes into a cupboard and the moment passes with the letter still sealed. A scheduled letter fixes both: "Open when you miss me" becomes a letter that arrives about six weeks in, on a Tuesday, when the novelty has worn off and the second wind has not come.

If this landed on a rough day, good, that is what it is for. You are about six weeks in, which is the week the house gets loud and the calendar gets quiet. Put the kettle on. Call my mother, she has been dying for an excuse. Somewhere I am thinking about that chipped cup and grinning like an idiot.

The One Sealed Letter: Where the Just in Case Letter Fits

Some people will not write this one, and the reason is usually the same: writing it would feel like sealing the deal. If that is you, that is allowed. You do not have to argue with a feeling that strong, and the other four stand on their own.

The real ones are rarely about danger. Pat Tillman wrote his in 2003, before a deployment, and left it on the bedroom dresser; his wife Marie later built a book around it, The Letter, published in 2012. One line from it, as she has shared it, is five words long: "I ask that you live." A sealed letter is not about the risk. It is permission.

In 1982, before leaving for the South Atlantic, an Argentine major told his wife he had left two envelopes, one for her and one for the children, in case he did not come back. Two envelopes, because a wife and a houseful of children need different sentences. The full template is in the guide to the just in case letter.

What Never Goes in Writing

Every letter in this set, sent or scheduled, follows one rule: nothing in it can tell a stranger where you are, when you move, or who you are with. No dates of departure or return. No locations, place names, or landmarks. No unit movements, ship or base names, or timings.

Scheduled letters follow it too. Write them so that nothing in the words depends on where you are or what is happening around you that week. A letter that could only be true in one place has told a stranger something. The homecoming letter says I am back, not I am back on the fourteenth. Your unit's briefing outranks anything on a website. If they say less, say less.

Writing Before Deployment When You Have Three Days, Not Three Weeks

Sometimes the notice is short. Here is the order.

  1. The homecoming letter, twenty minutes.
  2. The letter to your spouse, one page.
  3. One short letter per child, ten minutes each.
  4. One tour-calendar letter for the biggest date you will miss.
  5. Your parents, one paragraph.
  6. The sealed letter, only if you want to.

Everything else can be written on the quiet days from wherever you are. Spend the last night at home on the people in it.

The Homecoming Letter

Nobody puts this one on a list, and it may be the best of the set. You write it before you leave, to be opened the day you are home: handed over at the kitchen table, or scheduled for the day after you land. Coming home is stranger than leaving, and for a few days you may not be able to say much; the letter says it for you in the voice you had before. Put three things in it: what you missed most, one promise for the first week, and thanks.

I wrote this before I left, so if I am reading it to you now, the plan worked. Here is what I missed most, in order: the sound of the kettle, the dog's dramatic sigh when the lights go off, and the way you all talk over each other at dinner. This week the bin is mine, and I want to see every drawing. Thank you for holding this place together. You did the hard tour. I am home.

Recording a Few in Your Own Voice for the Kids

Even children who can read for themselves would often rather hear you. Before you leave, record the way you say goodnight, the birthday song, and the bedtime story you do the voices for. Record that one twice, so there is a spare for the night the first gets played to death. Record in the kitchen with the fridge humming and the dog's collar clinking; that noise is home. Keep each under two minutes, say their name at the start, and leave the stumbles in. Then give each recording a date, like the letters.

Setting Up Your Deployment Letters

Each letter has to reach one person on one date and stay private until then.

This is what Goodbye App was built for. You write each letter, or record it in your own voice, choose who receives it, and set the condition: a date you choose, or after you are gone. One letter for each date you pick, delivered by email on the day you set. Until it sends it is completely private, and you can edit, reschedule, or delete it at any time, including from wherever you are if you have a connection. It is free, it works on the web and on Android, and it comes in 13 languages.

The sealed letter uses the other condition: you can turn on an inactivity safeguard and choose a window between 3 and 45 days, and if you stop signing in for that long, your unreleased letters go out. If your tour has long stretches offline, choose the longest window, or leave the safeguard off and keep the sealed letter on a date you push back at each check-in. If the moment never comes, nobody reads a word of it.

Common Questions

What should I say to my spouse before deployment? Say the thing you keep not saying on calls, because calls are logistics. One page. If you are stuck, start with something small and true that is in the room with you: their cup, the noise they make getting out of bed.

What should I write to my kids before I deploy? One letter per child, pitched to their age. Little ones get a job and a squeeze to pass on. School-age children get a task and an inspection. Tell teenagers once, without a lecture, that they do not have to be the adult in the house.

How many letters should I leave? Five is the set: one for your spouse, one for each child, one for your parents, one sealed, and one for the homecoming. Add one for each date you already know you will miss, and stop there. Fourteen letters written in a panic on the last weekend are worth less than five written properly.

Is it bad luck to write a just in case letter? Some people feel that it is, and the feeling deserves respect. If it would sit badly with you, skip it; the rest of the set has nothing to do with risk. If you do write one, keep it short and about permission.

What do you write in an open when letter? Write for the moment on the label, not for the whole deployment. "Open when you miss me" is a letter about a chipped coffee cup and a bad Tuesday. "Open when you need a laugh" is one story you have never told them. Schedule it for the day you expect that moment and the envelope stops being necessary.
