Referring to our frequency tables as a check on suppositions, we find everything agrees well enough if we assume the first line to read:

UNAFUERZA DE CABALLERIA ENEMIGA

We will now put the newly found letters in the table. The letters previously found are in capitals and the new letters in small letters. The addition of D (=U) to the first alphabet permits us to add all the letters of the other alphabets to the first by the methods already discussed. Each of the other letters may then be added to every alphabet by these methods:

4th t xhgOLjQEI MSr D C U
5th t xhgOLjQEI MSr D C U
6th t xhgOLjQEI MSr D C U

One alphabet checks another in this way and we find everything to fit so far. We will decipher a few words more of the cipher message by the above alphabets and see if we can determine some new letters.

Again referring to the frequency tables the first word is evidently PROCEDENTE. We have also HALLA and MARCHEUSTED. The letter B may be determined from another cipher group, JFBSQDLD (56123456) = POSICION. The letter N may be determined from BETNDQXUC (123456123) = SERRADERO. The letters F and Y may be determined from JCPJOISLYDUASIUPF (23456123456123456)= COMPANIA PARTIENDO. The completed alphabets, arranged as before, are:
