Is there a reliable account of the organization of the Alamo garrison during the siege? Such as regular units, volunteer units, artillery crews, US volunteers.

Others will have much more information on this subject. I am new to studying the Alamo, but have an intrest since my 7th grade students are preparing a scale replica of the Alamo, it's defenders and the Mexican Assault columns under Santa Anna. However, i have some information and some fair guess work. I have heard it mentioned that their were 11 men in the mission manning the cannons there. Also, it would seem to make sense that the groups that arrived to gether would tend to band together (this is pure speculation). So I wouldn't be surprised to see the New Orleans Greys clustered together, Crocketts men clustered together, Travis' men, Bowies men etc. etc. The only question would be which guys and where. I would also surmise that most of the men who had been with Jamison were the cannoners.

Short answer on this one is go to the FAQs and "Defender Numbers". As to where the various units and individuals actually were, it would be reasonable to infer that each had its own alarm point where it was supposed to go at the outset of an action, with the expectation that they would be redeployed once the actual point of danger was known. What each unit's post was we simply don't know, but there is a pretty shrewd suspicion that apart from the gunners, nearly everybody who made it out of the barracks simply headed for the north wall at the start, and that resistance started to collapse when Morales got in over or through the southern defences, at which point those who could make it out tried to get away to the east.

I disagreee with the assertion that the defenders all ran to the North wall. Travis did, but I believe most of the defenders would have gone to their intial positions.
My knowledge base is poor. But I'll have a go anyhow. I would agree that they would have posts that they would go to (if in fact they were far from them once the assault began).
However, my understanding is that there were four columns attacking four sides of the alamo; And that they were initially unsuccessful in the assault. This would imply that they did not all rush to the North wall. In fact, I belive it would make more sense that the majority of defenders were static in their positions along the perimeter of the Alamo. I think this for several reasons 1) There wasn't enough room on the North Wall for all of the defenders- their was a limited capacity for the number of defenders who could defend that wall. (In fact, I think that is the reason it may have been chosen as the best wall to attack- had a limited firing front) 2) the reason for the intital repulses of the east and west wall columns would be the direction of the fire towards their flanks from the defenders who were not to their front. This 'pushed' them towards and away from their primary objectives, and made assaulting the North Wall easier. So, for this to happen there had to be defenders along the entirety of the west wall and eastern positions; and by logical extention, the southern positions (Main gate and palisade). 3) The funeral pyres of the defenders show that two groups fled the Alamo before being killed. The one to the west would indicate to me that defenders of the west wall were 'pinched off' by the advance of the Mexicans over the Northern wall in combination with the advance over the 18 pounder position. In short, they were cut off and their best hope was going over the west wall to safety. This would seem to support the idea that there were many defenders on the west wall.

I am afraid that I have to agree with Stuart on this one. When you subtract the gunners that leaves something between 80-100 riflemen to defend a perimeter about a third of a mile long. Not very many considering that they were armed with weapons that could on average pump out about three rounds a minute providing that rifleman was skilled in the use of his weapon.
There was obviously something up north that caused some confusion. It could have been the darkness. It could have been very effective defensive fire. It could have been a poor choice of attacking formations. It could have been the early loss of key leaders. It could have been any one or more likely all of the above. I think the evidence does suggest however that the northern area was more heavily defended than the rest, which lends a lot of weight in my mind to Stuart's views. Always keep in mind Stuart's tag line at the end of each of his posts, and add in a little of the natural instinct to "ride to the sound of the guns"
I have always seen, and perhaps I am wrong, that the battle for the "north" wall was not a battle for that wall exclusively at all. But rather, the northern action actually included the area from the cattle pen along the east side to about one third the way down the west wall, in a horseshoe shape with the top of the horseshoe about where the battery was emplaced in the center of the north wall.
All of your speculation, and I don't think I missed anything, could easily fit into what I just outlined. By the way for someone who admits that he does not have much information on the battle I think you have done a pretty decent job of envisioning it in your mind, and afterall that is what it is all about.
I noticed that you have asked some ORBAT questions. Alan Huffines in "Blood of Noble Men" has a pretty decent recap of defender organization. I would post it for you but my copy is presently lent out. Perhaps if he sees this he will be good enough to post his stuff

Thanks for the props Chieftan. Having my class build a scale (6ft = 2.5 cm) replica of the alamo and it's attackers and defenders has led to many ideas.
I agree with your horshoe analogy. My guess is that the thrust of the attack was along was just like that. With the Southern columns main role being to pin the defenders to the southern half of the defense.
However, I believe that there had to be defenders below this horshoe along the east and west. I think this because the accounts and the Map (+ the model) seem to imply that all four columns rebounded from their initial assault. What made them act so? To the North- the concentrated cannon fire. To the south- the obstacles in front of the pallisade combined with rifle fire. To the East- The fire from the horse coral, Mission cannon, and the combined fire from the long barracks/hospital/cow and horse corralls; caused them to veer north To the West- the fire from thos defenders + the 18 pounder would cause the attackers to veer north as well. (this is what I think Navaro's map is trying to show Cos' men to be doing).
This is why I think there were plenty of defenders to the south of your 'horshoe'
Or, as Longstreet said "troops are as nervous as a virgin about there flanks".
The result is that as the mass grows to the North (and as the rate of fire from the defenders slows); the number of troops overwhelms the rate of fire that the Texans can bring to bare.
I disagree with you estimate of the number of Texans who were maning the cannon. Outside of the guns in the Mission and the 18 pounder, I seriously doubt that the Texans ever tried to reload and fire the cannons once they had fired their intital blast. I think in the situation, they would have used the weapons they were comfortable with- the rifles. They would have been reluctent cannoneers at best. I don't think the estimate of 5-6 men to a gun applies here.

It may not be correct, my guess however is a good as anybody's, that the northern attack was the pinning attack and the breech of wall on the southwest corner is where Santa Anna placed his money. About a month or so ago on this forum, I forget what thread, we discussed this issue (southwest corner) in depth. This is a typical light infantry break and enter operation, and the troops that Santa Anna allocated to this are were probably his best.
I would agree that most if not all of the artillery fired only one or at most two rounds, save the guns at the rear of the church, which probably had targets exposed for a longer period of time. Perhaps not. The Mexican infantry probably got under the guns (the inability the adequately depress the piece) quite quickly.
I suspect that there were a few troops that retained their positions on the wall. Coming up with any figure is next to, no, impossible to determine. I think a lot of this would have to do with how much discipline they have. The correct thing is to thin out your force and honor the threat. This is quite hard to do with trained forces and excellent leadership. I will leave it to you to decide if either of those elements were present.

It's been a while, but as I recall we have little evidence/Mexican testimony of much cannon fire from the Alamo that morning. Aside from the blast that hit the Toluca Battalion, I can't think of any specific Mexican references to damaging Alamo cannon fire. The emplacements at the rear of the church were one factor steering the Mexican attack away from that area and toward the weakened north wall, with the Morales attack at the south end the kicker. I agree that this was a key part of the plan. Although there was at least one cannon in the tambor, I'm not sure which way it faced; I can recall no evidence of cannon fire hitting (or even being directed at) Morales. I think a large portion of the Alamo force was taken by surprise and may well have been asleep when the attack came, although there was clearly some presence on the north wall if that shot at the Toluca Battalion got off.

Stough: I have re-read your posts this morning and I have the following comments:
In looking at them again I get the impression that you envision that the attack in the early morning hours of 6 March was an attack of the entire perimeter. I do not think this is correct, although Mexican forces started from each of the four cardinal directions. To attack the entire perimeter would violate the principle of mass. I do not believe Santa Anna had enough forces at hand to do anything but attack specific objectives within the fort. I further believe that two of these attacks were driven from their initial objectives toward the north. It would seem reasonable to assume that the two objectives they were driven from, for reasons unknown, would be the small gates on the east and west side of the plaza. Neither of these two gates are that far from the north wall.
In the south, the objective was clearly the southwest corner. The fact that the 18 pounder was there I do not believe had much or any bearing on the selection of this objective. I think the real factor is the concealed, if not actually covered, avenue of approach was the deciding factor. Despite the popular view that the palisade was weak, and I do not share that view, I doubt that any effort was made to attack it, and anything in that area was diversion only, and I don't see any convincing evidence that there was even that.
Just about everyone talks about the 18 pounder. Was it really that much of a threat? Keep in mind that this gun was rather large, mounted on a small platform, with little in the way of ability to traverse. Staying out of the cone of fire for an attacking force who knew it was there was a piece of cake. I believe, and the acolytes of Saint Barbara can get me straight on this issue, that the 18 pounders great ability was in counter-battery and H and I fires.
As far as the larger issue of all around defense coverage, we know from S.L.A. Marshall's analysis of a later war (Men Against Fire) that soldiers in danger and under fire tend to bunch up for the illusion of safety in numbers. This is an area that takes constant training and supervision to overcome. While I am admittedly drawing this lesson from WWII that does not change the fact that it is a human thing rather than one unique to only one era. Allen will tell you, I am sure, based upon observations from his recent trip to Little Big Horn that it was just such a bunching up that contributed to Custer's defeat along the great length of Battle Ridge. Keep in mind here the bunching up of small forces is far different from concentration of forces.
I would love to see the finished model. Perhaps we can talk modeling technique in PM's as I am a ship modeler and always looking for new ways and methods to present my subjects.
Look forward to your reply.

Second the recommendation to check out Huffines' footnote in Blood of Noble Men. It's probably as close as we'll ever come to knowing the actual organization - short the finding of the original muster rolls.
As far as actual locations in the Alamo, there's a specualtive topic discussing this somewhere on the board. But, there is no real factual information on where anybody but a few indiviuals were on March 6th.
Using the primary sources there is absolutely no evidence that the palisade was attacked after the initial skirmish on Feb 25th.
Contrary to Hollywood's picture of men sleeping at the walls, I would submit that other than the guards, the rest of the garrison was sleeping inside the barracks and other buildings. The protection from howitzer fire from the buildings' walls and overhead cover from their roofs being the primary reason. After the chaos of the first day, I think it would be a safe assumption that Travis reassigned sleeping arrangements to place men (companies) as close as possible to their assigned defensive positions.
That said, I think a large percentage of men when awakend, and realizing that the attack was largely in the north would have moved to the sounds of the guns.
There's been quite a bit of debate about the breakouts, (check the FAQ) and while nobody can say with absolute certainity that no breakouts occurred to the West, I think it's a pretty remote possibility. When looking at all the evidence, it seems that Santa Anna actually planned to force the defenders to breakout to the south and east, and thus the posting of one of his senior generals (Sesma) and the bulk of his cavalry to intercept these expected escape attempts.

... The funeral pyres of the defenders show that two groups fled the Alamo before being killed. The one to the west would indicate to me that defenders of the west wall were 'pinched off'... I've never heard that the location of the funeral pyres were somehow related to the breakout attempts. My understanding is that both pyres were south and east of the Alamo compound. What are you referring to when you say "the one to the west.." I like your theory that it was flanking fire from the southern half of the west and east walls that forced those two columns northward.

George: I have no problem with the flanking fire from the chapel and the area to the rear of the long barracks pinching off and driving northward the column from the east whose avenue of approach generally followed the present Houston Street.
As to the west wall, where would this flanking fire come from? The only possibility I believe is from the entrenchment that covered the field piece in the approximate center of the wall. If that is the case then it stands to reason it was fully manned with a substantial number of riflemen. Only a few riflemen would not be able to place a high volume of fire that you would expect to be required. Of course you could carry this forward as an argument against the garrison being surprised.
It very well could be that Cos' column of two battalions just screwed up in the darkness in inadvertently headed a little further north than intended. Easy thing to do.
I guess that is what makes this interesting. You are never sure of the things you do and don't know. Good thing though is that it keeps you coming back for more.

Herb: I fully agree that there is no evidence to suggest an attack on the palisade. Morales had three companies in his provisional battalion, say about a 120 men. It would seem that about forty would be enough to allocate to the break in at the southwest corner. He had only two ladders assigned, which would not be sufficient for the employment of the larger force. The question then becomes how was the remainder employed?
This leaves us two possibilities. Either some sort of a diversion to draw attention away from the break in, or holding them in reserve to exploit the break in what Liddell-Hart called the expanding torrent defined as - concentration - initial penetration - lateral expansion - exploitation.

Chief, I agree with you that it would take something more than rifle fire to turn either column. Whether or not you could muster that much artillery fire along the west wall will depend on where you think the cannons were along that wall and whether or not you think they could have been angled in such a way as to fire on the attacking column. If Stough cares to elaborate on his theory, I’d enjoy reading it.

George: So would I. I think it is a fundamental mistake to dismiss anything out of hand without careful study. I too would welcome his elaborated views.
As to the guns. My information comes from maps, drawings, sketches, and models, as well as primary source testimony. This is probably no different from anyone else. Most sources agree that there were three or four guns along the west wall. The northernmost was most probably oriented to the north. There are then three at most we are concerned with.
Most of the material that I have seen suggests that two of these guns were in the northern end of the plaza facing west. The first one just south of the northwest corner. This gun, if it was there, and sources differ, would have been oriented to the front of Cos' column.
The second gun was, if my calculations are correct, just north of the center of the wall, again facing west. This would be the one protected in front by earthworks. From what I have seen this was a ground (as opposed to elevated) mount. This gun would have been in an ideal position to enfilade Cos' column save for its limited traverse. Were it mounted behind a wall, as most believe, it could only have moved its cone of fire slightly to the right (north).
That leaves the 18 pounder at the southwest corner. If they could acquire a target in the darkness, and if they could move that big hummer around quickly enough in that direction, then they could have had the desired effect. The question then arises would they, or were they more concerned with something else at the time.
All this stuff would be easy to answer, or at least intelligently speculate upon, if we had a definitive time line of events all over the field and how they were matrixed together - a moment by moment account. We don't and never will have this.
All in all though flanking fire from guns oriented to the west along the west wall is far more problematic then guns in the chapel area cutting up the flanks of the eastern column.
I am much more inclined to Cos' two battalions getting intermingled and confused in the darkness. But who knows.
