Greetings,

Thinking about a liner for a late war officer Union sack coat, campaigner. Any suggestions with regards to color, pattern, and what may have been the most common in 1865?

Also campaigner - would a brown civilian shirt be common (also Union impression)?

Thanks,
 
An officer's sack coat would be a private purchase deal so it could be lined with any good quality fabric/cotton. As well as a shirt, an officer would buy his own so any good quality period correct shirt would work. For enlisted men most campaigner events require you have a Federal issue white domet flannel shirt or the Federal issue grey wool flannel shirt.
 
Thank you, sir. Good to know. I just didn't know if the sack coat liners leaned towards the lighter or darker colors in 65' (or they simply varied, it sounds like). Much obliged for the information captaindrew!

Officer's frock coats were lined with a black polished cotton body & breathable natural cotton muslin.

It was uncommon to line a sack coat. The lining material would have been polished black cotton or raw cotton muslin.

This link is to a detailed essay on sack coat construction. Read more here.

An officer's sack coat was a commercial item that varied from the government issue. Needless to say, there were many custom features in a taylor made sack coat.

As the sack cost was a utility garment, the officer version typically did not vary far from the government issue. A finer grade of woolen material, appropriate buttons, staff officer e.g. & a deep patch pocket for holding maps instead of the issue hidden pocket.

Interestingly, only the sleeves were lined with raw cotton muslin, if at all.

Unlike cotton. Which soaks up moisture, wool is a very efficient wicking fiber. That makes sense when you think about it.

If wool did not wick water away from the skin where it could evaporate away, a wet sheep would die of hypothermia or freeze solid.

For both keeping dry against cold & wicking moisture to encourage a cooling evaporation wool is ideal. As a result of the wicking, an unlined sack coat was more comfortable than one with a damp cotton liner.
 
The lined vs unlined sack coat debate has come up before and there was an interesting discussion over on the Authentic Campaigner site. I've always understood that the lined coat was more prevalent. Now this is strictly on enlisted issue coats mind you. A guy over there did the research, I'm off to work so can't go into details, but lined coats were issued 3 to 1 over unlined. Existing surviving examples support this even though regulation specifically says coats to be unlined. The concensus is they held up much better if they were lined and there was plenty of scrap fabrics available to use up for lining. From personal preference for whatever is worth with both Federal and Confederate coats/jackets I greatly prefer a lined coat/jacket, even in warm weather.

That is what I have understood to be the case, many more issued lined sack coats than unlined. While in civilian fashion, unless a true working jacket, you can expect lining.
 
Gentlemen,

Thank you for the responses. In short, the takeaways in a snapshot would appear to be the following to summarize (if correct):

- Officer sack coats, if lined at all, were more than likely black cotton or the muslin (but, since they were private purchase patterns / colors could potentially vary, such as wool, etc.),
- Most of these utilitarian field coats were not lined (more comfortable in the long run).

But, as captaindrew mentioned, perhaps more were lined than regulations would state but each coat varied from soldier to soldier & whom you're trying to portray if a specific living history character.

Interestingly, only the sleeves were lined with raw cotton muslin, if at all.
Breathability of sleeves is very important, as is, whether the coat is to be a warm winter coat or a lighter spring (or work) coat, is having a lining; with a balloon sleeve style especially, a lining the same size (or a bit larger than the cut of the sleeve) helps to fill it in, and give it some depth.
Patterns around 1865 typically have no smaller than 9" at the elbow, with no more than 12", keeping in mind that the height of the style was around the start of the decade. This means that sleeve is pretty roomy! part of the proper construction is having that lining there.

Here are the sleeves on a c.1865 pattern sack coat I began two weeks ago. Close to finishing - I did the sleeves as one of the first completed parts of the coat, which proved to speed the pace of work up, as the main work still left is inserting the sleeves and sewing buttonholes.

Pay attention to how the sleeves look flat
- I attached the lining by hand, and it is larger than the cut of the sleeve (widest point 9.2", total length from top of the seam to bottom of the cuff, ~28". I intentionally made the sleeve long so that I have much more room for adjustment when attaching them, rather than for example having them too short - and being able to do much less about it!)

Still a work in progress - don't worry, the imperfections will mostly, literally be ironed out! This is a fairly hasty coat I am making for personal use, a quick, nice-looking coat that can brave the rapidly approaching autumn weather.

There is a certain volume given by the addition of the lining; balloon sleeves look like wearing robes without them! So even unlined coats typically have sleeve lining.

As to the material - in my immediate example here, the lining is nothing special; just some cheap, natural brown cotton that I am using up the remainder of in this coat - body & sleeve lining all the same.
On its "sister" coat made from the same pattern I have on the way, much less finished - I do have raw cotton for the sleeves.

Raw cotton muslin is used for the sleeves both for breathability and durability; the reason for using polished cotton on body lining is because 1) it is a very fine material - having had the pleasure of seeing and touching original coats, polished cotton was made as quite a luxurious fabric. That leads to 2), which is that it is very comfortable (raw cotton muslin is not so much, and this is not the same cotton muslin used in shirt linen, which was generally very fine & 3) it is much better suited to quilting, of which the era from the 1850s-70s probably reaches its peak in ordinary coats. Any nice coat had quilted and often padded linings.
(And #4 - polished cotton does not really go well on sleeves! Sleeves are one of the main areas of the coat where the most wear and tear happens. Polished cotton is not ideal for anything that will be bent and moved around in, and much better for a body piece! It's like using silk for working trouser lining.. no!)

As for quilting - It's one of the reasons I love this era in particular - accurately, properly quilted and padded coats are extremely comfortable.

An example from a frock coat I made earlier in the summer - using some tartan, ordinary natural cotton because it is what I still had to use up - the results are nice, but not as good as if I had used some finer, polished cotton! Here's is the lining as it looked in the process of development:

You'll notice the back panel I did by hand here, the front by machine. Only basic patterns.

And how the actual coat ended up looking - I never quite finished it! But it looks finished enough from the outside:

As to the body lining - a last minute alteration included not actually installing the back pieces in the end here - which is not an inaccurate:
An officer's sack coat was a commercial item that varied from the government issue. Needless to say, there were many custom features in a taylor made sack coat.

As the sack cost was a utility garment, the officer version typically did not vary far from the government issue. A finer grade of woolen material, appropriate buttons, staff officer e.g. & a deep patch pocket for holding maps instead of the issue hidden pocket.

As to body lining - something you will see in many original examples of US frock coats is a similar lack of back panels. Even when there is a complete lining in a frock coat, 9 times out of 10, the only layers on the back pieces will be the coat fabric and the lining fabric - intentionally contrasting with the layering on the rest of the coat. In a very structured front, i.e. like here, this makes for great ventilation as an open front billows air through, more or less allowing the "vents" at the back of the coat to act as actual vents and allowing for ventilation even if buttoned up.
While this is frock coats I am talking about, the same logic is often used for many sack coat styles, and indeed I am also incorporating into the pair of sack coats I am currently working on. This enhances breathability by a lot. Which is why the images I took here (Around 90 degrees Fahrenheit with no air conditioning mind you!) were done in relative comfort. It turns you into your own air conditioning! 😁



All of this applies to one extent or another, as this is civilian fashion, and often is incorporated in the wide range of private purchase in the war, from officer's sack coats to the odd custom uniform of an enlisted man. There are of course, other examples of plenty of frock coats with fully quilted, padded back panels (i.e. as was quite literally my original plan with the aforementioned frock coat) so this isn't a strict rule, of course. But it is the purpose and effect.

Hope this insight and viewpoint helps at least slightly! In short, a brief explanation and contrast between a sack coat in the works, made with haste (and largely with machine) in two weeks vs. a mostly handmade frock coat I took 2 months for.

Particularly incredible example of one of Lincoln's overcoats displayed at Ford's Theater - look at that brilliant, patriotic quilting! Much easier and displays better with polished cotton. Quilting on coats, be them military private purchase or ordinary civilian coats of all sorts, range from simple lines and basic patterns to highly intricate designs. I've seen many great examples of both machine and handstitched examples.

Thank you gents for the many good responses; very informative & appreciated indeed.

On this topic, attached are a few quick pics of some gear that I've been putting together if anyone cares to critique. They are: Federal field jacket, a brown civilian shirt I just picked up, modified gauntlets (I had a leather shop make expanded cuffs), and a few sample liner colors in front. Are those plaid colors too 'loud' for 1865? Probably a plain liner best or are these acceptable?

Thank you again for feedback - the good, the bad, & the ugly are all helpful and constructive! 😉

There are plenty of museum examples of colorful coat linings in menswear; it is one of the few places in the latter 19th century where color is really acceptable; "loud" waistcoats for the most part do not survive the 1850s, and generally colors are much more mute than previous decades. We do also, i.e. again, Horse Soldier if not various museum collections online show custom uniform coats with patterned linings.

What I would be concerned with here though is the nature of these plaids. Are they woven in or printed patterns? If the latter, not really representative or common at any point in the century. Usually also, your fabrics on all body pieces match, and the two sleeve linings are different to them (but the same on each sleeve). Or, lining is all the same. The former is most common for anything with a lining well into the 20th century. If you were asking as to which if these are our choices, both look good honestly.

I'd be sure to use a natural material (Goes without saying of course) for best results as regards breathability and comfort. Also, where's the coat been? Looks like it's seen some great use!
 
Thank you for the response & info (playing a little catch-up), but, yes, I love the colors, styles, fonts, architecture, etc. used throughout the 19th century!

These plaid designs appear to be simply a printed pattern to be honest. But, good to know between the two options. I was in the shop 'Needle & Thread' just outside of Gettysburg and they directed me to the 'Civil War era' section of common patterns. As for the color(s) themselves, I was worried that they'd be 'too light' in that I should tone it down to more of a drab shade perhaps, but I certainly value your expertise if you feel that these design colors would be accurate. That's why I love this forum - I knew that I would get quality insight from the good folks' here! 😊

As for the coat, lol, actually it's brand new - I recently worked on the upcoming CW film, 'Gettysburg 1863' breaking in uniforms, etc. Attached are a few pics from the projects that I did:

- The trousers were brand new too, but they had to look heavily used for the movie,
- And, since I couldn't find gauntlets made with expanded cuffs anywhere in these mainstream sutlers, I simply bought yellow gloves from one of their stores, cut it at the wrist, had new leather made for the expanded cuffs, and then blended it all in to look battle worn on film. I've also done battle flags & leather boots before, which turned out nice. But, whew, they were a bear to do!

Thanks again for the feedback! 👍

What I've seen of civilian shirts and coat linings, basically anything will do for homemade/custom/private purchase stuff. As long as it's a readily available period cloth, in a readily available natural period dye, and period pattern you're good. Most coats would have been lined with leftover/whatever shirting material was onhand, unless something specific was procured or specified.
 
Interesting info, thank you for sharing, 👍. Especially if it's 'private purchase,' that purchase, like you said, could have been anything....
 
I'm no tailor or seamstress, so grain of salt, but I'm fairly sure it wouldn't have been too difficult to cut and sew an old shirt into a jacket or coat as a lining. Again i very well may be wrong about that.

No no, don't worry - you are correct. I have even done this before. Today much as then, wastefulness does not pay! I have reused some nice shirt linen for linings and you can definitely recycle it that way... the problems can come in cut, though, i.e. only the largest pieces of the shirt (of course) are normally useful. I don't think I've thrown away more than about 10 inches worth of fabric, most off cuts I've kept around in case they might be needed.

That is very interesting - cool to communicate with someone working on the film. Only first heard about it a few weeks ago!


As to the fabrics - Needle & Thread know their stuff, these are accurate, or at least look to be from here - but not common when compared to woven fabrics. Among shirts in particular there is certainly gross overrepresentation in reenacting, including the patterns that I usually see. These patterns look fine, and still can be used; it's the fact they are printed that makes them less common though. I have shirts of both kinds. At the end of the day for this it should be up to you.
 
I stand corrected - this liner material is actually 100% woven, 😮 (yay, lol).

After this discussion, I did little more research on it and, happily, that's what it is. I'm glad, and grateful, for the responses here on the forum because it helped to prod me to inquire more just out of historical accuracy sake, plus, I learned something new about this craft - much appreciated!

As for the shop 'Needle and Thread,' the owner is an older woman (90 years old?) who assisted in getting me this material. I'd recommend them hands-down.

As for the film, yes, it arrives in theaters in just two months already. In addition to working on the props, I was also fortunate to have been an extra in a few scenes. Hopefully mine aren't edited out, 😉. The main premiere is at Gettysburg's Majestic Theater on Wednesday, Nov. 11th. Should be a big event - maybe see you there....

That is all brilliant news. Glad the fabric can work - it looks very aesthetically pleasing anyhow, so a bonus. I'll be tuned for the film, and at this point if I ever visit Gettysburg town I'll have a list of places to see! It has been an interesting thread, thank you sir!
