13 June

A force of 4,000 Indian troops, accompanied by a British battalion, approaches Sacramento. They come under fire from two field guns mounted on top of the levee, and their advance is checked by this and the knowledge that there are troops defending the town.
However, the Imperial force has an important force multiplier - the Grappler, an Albacore-class gunboat with a draft of under seven feet, has been accompanying them on their trip inland. While she has barely inches under her keel this high up the Sacramento river, she is able to work her guns - a heavy 68-lber, a 40-lber (taken from Camelion) and a 24-lber howitzer all able to bear at once - and provide covering fire, which forces the American field guns to switch to firing on Grappler.
With their western-flank guns effectively rendered unable to contribute, the American defenders - the 1st California Infantry, 5th California Infantry and two regiments of California Volunteer Cavalry - are a little more nervous about the coming action. Nevertheless, they decide to make a fight of it, and have the advantage that the Volunteer Cavalry and 1st Regiment at least are well drilled.
With the terrain around the town quite flat, Carleton determines that it will not be easy to win an open field battle against superior numbers. As such, he has his infantry hole up in Sacramento, and makes it a street fight where every house is a potential fortress. This results in a bloody battle, with the skills of the Gurkha regiment proving useful to the British, and the battle occupies most of the day - with one notable moment being when the Grappler dismounts her 40-lber gun and begins using it as fire support from the levee position defended by small-arms men.

Ultimately, Sacramento is captured, and the bloodied California infantry retreat upriver. The cavalry covers their escape, and the British do not pursue for now.

(As it happens, if the British had attacked earlier they would have been able to literally sail their gunboats into Sacramento town square - the whole town was several feet underwater during the floods of the early year - but Maitland was unwilling to make the attempt before his troops arrived and so missed the chance.)

The Charleston -formerly the Ville de Nantes - arrives off Halifax, and puts in to recoal. She needs quite a lot, having been undergoing a 'shakedown' on the way across the Atlantic and averaging nine knots for her passage - as such she is very low on coal.
It will take her two days to coal up, but it is at least cheap (Halifax has a working coal mine and as such the coal is not very costly). While she is there, several blockade ships enter or leave Halifax - including the enormous Warrior, here to recoal and escorting three prizes.


Lee's army begins manoeuvring to capture Harpers Ferry. On the first day of the action, Confederate forces push the Union defenders off Loundon Heights and cut the Baltimore & Ohio railroad - thus allowing artillery to begin bombarding Harpers Ferry once it is emplaced.


15 June

Approximately 3,000 of the garrison of Harpers Ferry manage to evacuate ahead of the advancing Confederate troops. The rest are cut off, and start coming under bombardment.

McClellan's nearest forces are about thirty miles away, and after consideration he decides it would be foolish to send one corps south to attempt to rescue the Harpers Ferry garrison - it would simply throw more men away. Instead - after sending another letter requesting better equipment - he largely ceases training operations and begins concentrating his army at Chambersburg.
The one thing McClellan does not want to do is to easily surrender the advantage of the defensive. He considers himself to be heavily outnumbered, and that he will have to fight carefully to avoid being destroyed.



16 June

Harpers Ferry surrenders, under artillery bombardment and with Confederate riflemen working steadily forwards to the west of the town.
Lee and Cleburne examine the results carefully, with an eye to discerning which of their new practices are successful and which are not. Particularly notable on the successful side of things is the use of skirmishing sharpshooters to defeat isolated pickets - almost without losses - while the accuracy of the artillery is still something which needs work. (Lee notes that his infantry are now longer ranged than his artillery, which is not entirely accurate and which offends his artillery commander, Pendleton.)

Both sides are now struggling to sort out their logistics to move the rest of their armies forwards. The railroads and rivers in this area run counter to the 'grain' of the land, so both Lee and McClellan need to rely on wagon trains and supply depots more than railroads.



Also on this date, Eads finishes casing the Pennsylvania. She is ready to fight, though the decision is made to keep her back until the New York and Massachusets at least are able to support her - single ironclads are clearly not a winning proposition against the powerfully-armed British ironclads, and in any case there is a debate on whether to use the 'United States' (Pennsylvania) class to open the Chesapeake, to attack Gosport or to clear the Potomac.

does something big happen? because IIRC it wasn't long ago when the suggestion of seeking peace by a member of congress was harshly put down.

Here's something to think about.

At this point, the Union has two things it largely lacked over the course of the last few months.
Specifically, it has:
A credible army - the Army of the Potomac has been begging, borrowing or outright stealing units from other areas and pushing their more broken-down regiments on them in return, gambling that all it really takes to defend e.g. Philadelphia from amphibious landing is warm bodies to put in the way, so McClellan has managed to rebuild his army's morale.
And, when it's unveiled in a week or two, a fairly credible East Coast navy in the shape of the Eads Boats (which have been pretty much distorting the industrial output of the Union to get them cased as fast as possible, meaning some degredation in rail line repairs/construction and the like, but they do have them nearly finished.)

Unfortunately, those are both still very fragile things. The Union doesn't have Martin's Shot, so their response to large wooden ships is not ideal, and their army is of course not particularly well armed.


Now, if I may, a rather silly bit from Tsouras.

https://books.google.co.uk/books?id=HmF4BwAAQBAJ&pg=PT33&lpg=PT33&dq=68+pounder+charleston&source=bl&ots=dCAuS_7cX5&sig=0E0sYoWh4fpJ2WA3ppgNLMe12to&hl=en&sa=X&ved=0ahUKEwjg3JvFme_OAhWB0RQKHY78ByQQ6AEISjAI#v=onepage&q=68 pounder charleston&f=false


In referring to the "old 68-pounders" being unable to damage Union ironclads and that they then have to rearm with "more powerful" 8-inch and 10-inch guns, Tsouras is being rather silly.

In the first place the 68-lber (95 cwt) is the best anti-armour weapon of the period not called the Somerset Cannon. (It's more effective against the armour of Warrior than any American gun apart from a point-blank-range 15", and at longer range the faster velocity fall-off of a 15" renders it less effective.)
In the second place having the British replace them with 8" and 10" guns is basically saying that the American approach was correct and that the British only have a hope by copying them.
And in the third place it misses that the 68-lber is an 8" gun. It's a high velocity 8" smoothbore which burns more powder than the American 11" gun with less surface area of impact.

I also see that earlier in the book he describes New Ironsides as having twice the firepower of Warrior on half the displacement, and as having battered Black Prince to death outside Charleston in the previous book; this would be a hell of a trick as the 13 68-lbers and 5 110-lbers on a Warrior-class's broadside burn between them something like three times as much powder per broadside (hence deliver three times the energy) as the seven 11" guns on the broadside of New Ironsides, and of course that New Ironsides could be pierced by the 68-lber gun while the 11" gun was incapable of piercing the Warrior without a powder charge sufficing to make it explode. Thus we have an American ship incapable of piercing a British one with her seven guns, a British ship with thirteen faster-loading guns able to pierce the American one, and it is the British ship which is defeated.
We will leave aside how the New Ironsides was essentially unsteerable for now.


It seems like the attention paid is all to the mass of the cannonballs and none of it to how fast they're moving.

Ah yes, the seven year old method of cannon design.

In all seriousness though.

I think, in essence, for the Army and the Navy, we've got to consider two things for each of them:

A) What the Union thinks they're capable of.
B) What the Union needs them to do.

Remember that B can influence A: As Imperial Japan has shown us, capability can easily be inflated as goals require if you're delusional. And desperation can induce delusion. If you lose the if your fleet can't do X, you'll be very inclined to believe that your fleet can do X. Espicially with things like 'Pride' and 'Honour' and 'Destiny' and 'Exceptionalism' and 'Elections' and 'Angry Public' and 'Politics' interfering with the thought process.

So, add C) How clearly they're thinking.
 
Those novels were the worst, especially the first one because the first 3/4s of it are just talking about how awesome the US is compared to the rest of the world.
Also, the war seems to be nearing it's final stages. I'm excited for what those two big things are, I hope one of them is Lee coming up with a "crazy enough to work" scheme and pulling off.

17 June

During a storm, the blockading squadron for the Delaware river is scattered. HMS Thunder - anchors carried away and without the power to steer - is driven into the shore, sustaining severe damage, and the old ironclad is found to be not in a fit state for refloating once the storm dies down - her keel is broken and the weight of the armour has distorted her skeleton.
As such, her crew are taken off by the Defiance. The guns, unspoiled supplies, and some of the armour plate are taken aboard for redistribution (or salvage), and what is left is burned.

Pennefather begins pushing down the rail line from Detroit. He moves slowly and methodically - he already has his major victory for the war, and does not want to risk being outmanoeuvred by the Union forces. (In truth they have little they could outmanoeuvre him with - there are three artillery batteries and a division in his way, and their small arms are mostly smoothbores).

The submersible vessel the Pegelius launches from Boston under cover of darkness. It attempts to reach the blockaders offshore and detonate a caulked gunpowder keg under the keel of the Duncan, though problems with the design mean it has to surface after an hour less than halfway to the target.
Boats retrieve it with difficulty.



18 June

Lee spends the day with Jackson and Cleburne, working out possible tactics and strategies for the coming campaign. Jackson volunteers information from the campaigns earlier in the year, offering insight into the behaviour of George McClellan - that he is a dangerous opponent, but that he is overly cautious. (In short, that he treats uncertainty as danger rather than opportunity).
Stuart is consulted on the capabilities of his cavalry, and the Confederate cavalry commander emphasizes a particular point - he has managed to arm all his men with rifled carbines, some of them breech-loading, and he is confident in his ability to defeat infantry so long as his men do not go up against large numbers of defenders at once.
About three in the afternoon, Lee comes to a conclusion - the caution of McClellan is both an advantage and a disadvantage to the man. It is an advantage as McClellan is very hard to destroy, but it is also a disadvantage as he is easy to predict - McClellan will always keep back a reserve, and will never allow his line of retreat to be cut off, and this very fact is exploitable.


The New York completes casing. A debate is ongoing as to what armaments to give each United States ironclad, as it is felt there will only be two of the heaviest gun (the 15") available.

For the fourth time this month, a supply line is briefly established through the Confederate siege line around Washington. This area of the siege is tenuous at best - the fort ring makes the area to be covered too large to permanently interdict - but the railroad is cut and supplies have to be fought through under heavy escort.

The issue is raised in Congress whether the government should evacuate to a safer location, further north; this is decided against, though the debate is close and it goes to a vote in the House. As the results are read out, the firing of Confederate guns at the Rock Creek line can faintly be heard.

(I considered putting a bit about Lincoln vetoing the adoption of Star Spangled Banner because of the third verse, but it seemed a bit heavy-handed.)

Aside - the Breech Loader in British service.


Basically, the British got interested in the BL gun in the 1850s, around the time of the Crimean War - this seems to have been because of a combination of Armstrong inventing his breech at this time and the independent reforming desire from the Crimean War.
He started with land service pieces (the 6-lber, 9-lber and 12-lber) and was then pressured to develop it to heavier, naval pieces.
There was resistance for all sorts of reasons - one rather comical one was that an accurate gun was less useful for barrages, as it would always hit the same place. Nevertheless the Royal Navy went pretty full-on in adopting them, and lots of ships had 40-lbers or 110-lbers by 1861.

OTL, what doomed the system was a combination of some people lacking enthusiasm for the whole concept, the real issues with breech loaders of the time (since the breech mechanism was a vulnerable point) and bad PR - the reliability issues of the weapon were very much over-exaggerated. It seems like people expected perfection out of it, and - when they merely got something very good - rejected it as imperfect and went back to RML guns. This same cloud also affected the field guns, which were never even as bad as the naval guns (indeed the Armstrong was almost as good as the Krupp guns of the 1870-1 war!)

TTL, however, the weapons have been used in a fairly major war. Their imperfections have certainly been highlighted, but so have the advantages (great accuracy at a longer range than for a smoothbore weapon, relative fast firing, and excellent penetration of land fort materials) so that the BL development chain is continued. This briefly leads to ships being armed with a combination of Armstrong guns (for non-armoured ships) and high powered RML guns (for armoured targets) until an improved breech is developed and the heavy guns become Armstrong-Elswick RBL pieces capable of anti-armour work.

More importantly, this means the Armstrong field gun is kept in service, and the only muzzle-loaders left in the British regular army are the ones carried by the infantry.

Bit more criticism of the Battle of Charleston from Britannia's Fist.
On October 7 (1863), American picket boats spotted the British strike force and raced back to inform Dahlgren. Seymour led a concentration of naval power not seen since the Crimean War, a full thirteen percent of the Royal Navy, roughly 8,000 sailors carrying 600 guns made up of the heavy ironclad ships HMS Black Prince and HMS Resistance as well as another three ships-of-the-line, five frigates, four corvettes, three sloops, a gunboat, and a gun vessel. Dahlgren had under his command 2,200 sailors carrying 114 guns, made up of the ironclad frigate USS New Ironsides, four Passaic-class ironclad monitors at Charleston and another five monitors at nearby Port Royal, the refitted ironclad ram USS Atlanta, two frigates, three sloops, eight gunboats, and the American Navy's top-secret weapon, two submersibles. By all appearances, the odds were heavily against the American fleet, but the British mainstay weapon was the 68-pounder gun which was only believed to be effective at 200 yards, while the Americans had 90 Dahlgren guns of the IX-inch, XI-inch, and XV-inch variety, which were viciously effective against both iron and wood. Additionally, both admirals had more on their minds than just the battle ahead - John Dahlgren's son, Colonel Ulric Dahlgren, had joined his father aboard the USS New Ironsides, and His Royal Highness Albert served as a lieutenant aboard the corvette HMS Racoon.

Okay, so, here's how I view that one:


Firstly, Seymour's strike force.

13% of the Royal Navy would be (numbers approx, I'm using the RN as of Trent):
British liners 60 - so 13% is seven or eight liners, not three. Three is 5%.
British ironclads 11 - so 13% 1.5. 2 is acceptable if a bit high, but his capital ship count overall is poor. Two is 18%.
British frigates 55 - so 13% is 7, not 5. 5 is 9%.
British sloops 81 and British corvettes 26 (combining the two categories) - 13% is fourteen such ships total, not seven. Seven is 7%.
British gunboats and gunvessels in excess of 200, so there should be roughly thirty gunboats/gunvessels rather than a pitiable two. Two is less than 1%.
This is not a concentration of naval power "not seen since the Crimean war". It's not even all the ships the RN had in North American waters OTL at this time - that involved five ships of the line at one point!

Secondly, Dahlgren's force.

New Ironsides is kosher.
Nine monitors deployed at or near Charleston is every single oceanic monitor the USN has.
Atlanta is kosher.
Two frigates is doable, as are three sloops and eight gunboats - but it's a huge chunk of the USN including every seagoing ironclad they possess except the Galena.
The US Navy did not have any submersibles.

So we have what is billed as 13% of the Royal Navy but is really more like 8-9% going up against the entire USN's ironclad force.

Thirdly, the 68-lber gun is described as only effective at 200 yards.
This is completely mad. The 68-lber gun with full "far" charge fires a cannonball going at twice the speed of sound, and it's able to punch through four inches of rolled wrought iron - it's the weapon the sides of Warrior were designed to defeat, in fact - and has a very long range for a smoothbore (Wiki gives effective range of 3,000 yards, against iron it would be less but it's still got a good carrying range.)

Fourthly, Dahlgren guns of the IX, XI and XV inch calibres are described as viciously effective against both iron and wood.
Wood, maybe, but iron no. The 9-inch Dahlgren was not considered a suitable weapon for use against iron armour, and the 11" gun never achieved a full penetration - indeed, Dahlgren himself tested the 11" gun against armour weaker than that on the Resistance and Black Prince and found it unable to pierce (you need to load it so much it would be more likely to explode inside the ironclad carrying it.)
Only the 15" gun would be able to penetrate the side of either British ironclad at all, and that only at very close range - certainly not the 800 yards which the 11" gun is shown penetrating Black Prince.

(It's also worth noting that the reload time of the 15" gun was so long in a monitor turret (~15 minutes) that each 15" gun would get off one shot before the British ships reached them... and that the 68-lber gun is shown as unable to do damage to the Passaics even at point blank range, when in reality the 68-lber would be smashing several armour plates at once.)

And fifthly, OTL the British removed His Highness from the combat area when Trent looked likely to become a war.

Worse, the Palliser shell concept was more than a year old at this time. With steel bolts as would be carried, the 68-lber could have completely penetrated the New Ironsides at close range (she's as well armoured as the Crimean Ironclads, hence vulnerable to the 68-lber at very close range.)

As for the Passaics...



Over the course of one hour of battle, the 11-inch gun on a Passiac will fire four to six times. The 15" gun will fire three to four times, and it will be highly inaccurate (the Passiac's gun ports do not allow the 15" gun to be sighted, it fills the entire hole). Over the same time, every gun on the British wooden ship (even with a heavy frigate that's a 26 gun broadside) will fire at least twenty times, meaning that the Passiac has at most ten hits with heavy guns and the British ship has fired a minimum of 520 shots back. This hail of medium shot will - even if not penetrating the turret - cause progressive damage, probably hole the side once or twice and jam the turret, and generally render the monitor unfightable.

The submersibles are just gilding the lily, it's not quite impossible given the technology of the time but it's very much a handwave for them to even exist.

Conclusion:
...sadly, Tsouras is relatively accurate as far as published Britain Versus Union books go. This is very faint praise, and it's this kind of thing which inspired the creation of this TL.

It's a nice picture, but sadly it's not very accurate. It's also got the problem that, well, most people in the comments are Wrong On The Internet.

ED: it's also probably the wrong post. Warrior and Monitor fought on page one - Warrior won, on account of having guns with more effective power and something like fifty times the number of damaging shots fired per minute.
 
If you think Tsouras is bad, stay away from Manifest Destiny: Lincoln Sneezed by Bryan Boyington. He has a super ship named USS Stonewall which is fitted with a 20" Dahlgren and enough turret armor to shrug off all British shot and shell. I had trouble believing there was a 20" Dahlgren gun but there were four of them cast. They weighed 100,000 pounds each (!).

https://en.wikipedia.org/wiki/Dahlgren_gun

He also has Lincoln getting through Congress a bill to rebuild the South, after a reconciliation meeting with Davis and Lee. (The title refers to his sneezing just as Booth fired, thus giving him a crease in the scalp instead of a derringer ball in the brain.)
