We have been working rather intensely with the Le Havre passenger lists of late. At the same time, we have received missives of bafflement caused by them. If you are reading this post with interest, we will assume that you have encountered difficulties accessing and understanding the Le Havre passenger lists. We will also assume that you have read our post about them with its update about the wonderful index to them, Désarmements havrais. However, many, many, many of you have written in frustration, having failed to find your ancestor or even the vessel, or even really, to understand how to use the two sites. So, let us try to clarify.
NAME OF THE COLLECTION - Inscription maritime du Havre, Index par bateaux des registres de désarmement, 1750-1876
ARCHIVES CODE OF THE COLLECTION - 6 P 6
WHERE THE COLLECTION CAN BE FOUND ONLINE - on the website of the Departmental Archives of Seine-Maritime (ADSM)
click on "Autre fonds numérisés"
click on "L'inscription maritime"
click on "Cliquez ici pour accéder à l’Inscription Maritime en ligne"
for Quartier, choose Le Havre
for Type de registre, choose Rôles des bâtiments de Commerce
click on Rechercher - That takes you to the collection
WHAT THE COLLECTION IS - these passenger lists are within a collection of ships' papers, or sea letters, a notoriously messy kind of documentation, even today. Every ship has to carry papers of registration, the crew list, passenger list, insurance, details of every port visited, etc.. In France, in the 18th and 19th centuries, every time a French-registered ship returned from a voyage, all of the ship's papers, which form the administrative history of the voyage, were turned in to the port authority. That is what the surviving collection is : the papers that the vessel brought back. There were other collections. There were papers of ship registrations. There were lists made of the passengers on all outgoing and incoming vessels and these lists were held at the ports. The ports, especially Le Havre, Brest and Lorient, were bombed heavily by the Americans and British during World War II and all of these other collections of passenger lists and ships' papers were destroyed in the bombing. This single, partial, surviving collection was discovered long after the war in a part of a building that was not entirely destroyed. It is very little but it is all that we have.
WHAT THE COLLECTION IS NOT - these are not lists of all passengers who left from the port of Le Havre, only of those who left on French vessels that returned. The papers, including passenger lists, of any vessel that was not French that sailed from Le Havre whether Belgian or British or American or Dutch, etc., will not be included. The papers of any French vessel that did not return to Le Havre will not be included. (Thus, if the vessel were sold after the outward voyage, or if she returned to a different French port, such as Bordeaux or Nantes, she did not return to Le Havre.)
HOW THE COLLECTION IS ARRANGED - Chronologically, by the year and date when she returned. Thus, if your ancestor sailed from Le Havre in 1848, you will look for the ships' papers in the year of return, 1849 or 1850. They are not in alphabetical order, but in the order that they were decommissioned, or désarmé. There are hundreds for each year, each given a désarmement number for that year.
HOW TO FIND A PARTICULAR VESSEL'S PARTICULAR RETURN - carrying on from the above explanation as to where the collection can be found online.
after clicking on Rechercher and arriving at the collection
click on "Rôles des bâtiments de commerce"
click on "Ordinaire (long-cours, cabotage, pêche, plaisance, bornage)"
scroll down the list (it runs to many pages) to find the year in which your vessel returned to Le Havre
read through the hundreds of pages to find your vessel's désarmement / decommissioning number
The minimum amount of information that you need is: the vessel's name, the year of return and the decommissioning number.

This is where Le Désarmement havrais becomes so very helpful. Not only have they listed:
- the names of the vessels
- the destination of the voyage
- the captain
- the crew
- the passengers
They also give, for each return from a voyage for each vessel, the date of return, the decommissioning number and, most preciously, the page number on the microfilm, so one need no longer scroll through those hundreds of pages. For the Mansard, above, that went to San Francisco in 1858, we can see that her decommissioning number is 178, that her papers can be found in the ADSM 6P6 series (which we already knew) register number 209.

Further down the same page, the wonderful volunteers of this index give the crew and one can click on "passagers" to get the list of passengers.

Here, you see there was only a captain, Auguste Abel Gravereau. Well, of course that cannot be, Dear Reader, and this is when we recall that this index, as marvelous as it may be, is a work in progress. There must have been a crew, we imagine, and there may have been passengers. So, we want to see the original ship's papers to see if there were not more to them or if they were partially destroyed.
Knowing that she returned to Le Havre in 1858, that her decommissioning number is 178, we can go back to the ADSM website, work our way to the year 1858, and choose the 1858 item (the second one, it turns out, numbers 96 to 190) that will include that decommissioning number:

Click on the plus sign to see more and you will see that you are at 6P6-209, which is what you know you want from the information given by Désarmement havrais.
Click on "Cliquez ici pour consulter le document" to see the images. Then, go straight to page number 637.

There, you will see the entire crew list and, further along, on page 642, you can see that there were four passengers.
There can be mysteries, as in the case of the Amitié, which arrived in New Orleans in 1837, and for which Ancstry.com has the full arriving passenger list but for which Désarmements havrais and ADSM have no passengers departing. With such a mystery, read the other documents, especially the last page of the ship's papers, showing all ports visited, and giving some notes, or observations. The Amitié's las page shows that, on the return voyage, she stopped at Plymouth, in England. In the "Observations" column, the note is partially obscured in the binding but it says that she was carrying dispatches, which the captain delivered to the French consul at Plymouth, along with some of the ship's papers. The entry on the right at the top shows the arrival in New Orleans on the 6th of October 1837, with "diverse merchandise" and a crew of twenty and 166 passengers. So, it would seem that Ancestry's passenger list is correct and that the French consul at Plymouth kept the vessel's passenger list, which is why they do not appear here.

Now, you are experts!
