1813 Campaign - Command and Control Information


Campaign Map for 29 October 1813

In the past I have tried to explain how the campaign administration is run.    It is really difficult to do so without seeing what I actually use.   The whole thing is too much to put on here, but this is an example of 1st and 2nd British corps on 29 October 1813.

On the map you will see that 1st corps is attacking 7th French corps at Ribadeo. 

2nd corps is moving south to Ourense.

I hope to explain what is involved in the issue of those two orders

Order of Battle for 1st and 2nd British Corps

This chart only shows the two corps concerned, there is a similar chart for 3rd and 4th British corps.

1st corps shows the commanding general as Stewart, who is an average commander

Each brigade is listed with the following information

Strength – at start of campaign
Class – A would be elite, B is average, C is poor
Fire – effective volley fire, A would be veteran, B is average, C is poor
Skirmish – skirmish ability, A would be riflemen, B is average, C is poor
Casualties – current casualties, always keep first 400
Garrison – if a brigade is detached for garrison duty

2nd corps shows the same information

But note that three brigades are in rout

Current Daily Orders

There are only three British depots at present

Santiago has been captured by the French, and lost their 3 days supplies
Ourense is the new main depot, they have received 7 days and issued 1 days
Corunna starts with 1 day, it receives 1 day and ends with 2 days

1st British corps starts the day with 4 days supplies
It does not receive any because it has orders to attack
It always uses 1 days supplies each day
It ends the day with 3 days.

2nd British corps starts the day with 3 days supplies
It has to retreat because it lost a battle
Therefore it does not receive any supplies and ends the day with 2 days

Campaign Comments
This is the information which will decide what orders are given to each corps.

If you look at the map you will see that 1st British corps is cut off from the main depot at Ourense, because the French have captured Santiago.

The only depot available to them is Corunna (covered by the symbol for 1st corps)
If you check the depot you will see that Corunna has only one days supplies at the start of the day.   And that is the only depot available to resupply both 1st and 3rd British corps.

I appreciate that all of the above is quite complicated, and I hope that I have been able to explain it well enough for you to understand the command and control information available to the CinC when he writes his orders at the start of the day.

I trust that you will also see that Wellington took a big risk ordering 1st and 3rd corps to attack Ribadeo.   If they lost the battle they would still have 3 days supplies, but they would only have Corunna to resupply.  And that depot only receives one days supplies each campaign day.

  2. Hi Bob

    Its a simple system, but quite difficult to explain
    And probably quite difficult for anyone else to understand!

    keep safe
