laying down that the use ot Arrq 08lls1r. Book "E" was to ceo.so w.e .. t. 1 Nov .ltlt., 

as it had been ~aecl(bl.oagestell.t • Tho system of allotting oai.lld.ga.s 

after that date was to be as follows -

Bn Bigs t-pa were themselves to work out a callsign table . (Rm'mllOHENvER1'EILER), part ot the oa.llsign plan (RUEZEICHiNPLAN), still on the 

basis of tables in the A1'm1' Oallaign 3i:>ok "E0

it to RBQ sigs, t~ where it would be passed to Div Siga Bn. From there it 

woula l!P to the CSO. After examination and any naoesaar,y alteration all tables 

would be retumed to bns by the same channels in time tor use by the f'L..-at of 

the month. In praatioe tbis system clid :not chapense altogether with the use 

ot Arlq CaJ.laign Boo'k "E", but al.lotnlE'nt of callsigns according to basic numbers 

was to ae diaaontinued.

then •re had been J109Ptographic "Zess-. Then 'I • 

went to ffittNEM.UNDE with the task at learning Russian and 

:Polish, -a.nl breaking the systeos of both those countries • 

.After 1-t years I went back to BERLIN, to the Russian 

_section. The Russians were using three syst~DB in t'lie' 

BALTIC, the IDDin syster.i, one 4--figu.re and one 5-f'igure 

system. · In the begimling, decypherJ.ng of the m;i.n system 

was successful.; in this cypher the Russians reported. in 

advance tc all units the intended IilCves of' ships and a/c 

wh:Lch were to -take place the follc\Ving dq. It was an 

unrecyphered 8l'stem, a code whose groo.ps "Were triplicated 

(.3-tach belegt) • 

W/T cesso.ges connected with th:L.s network could also. be 

traced in the second 4.-f'igure cypher. Tlu.s was a 

recypheri:ng system. The systera itself was not entirely 

decyphez'able, as the JiJB.terl.al wn.s insu:f"ficient; we only 

received a little of it ·nth heavy W/T 111terference. 

We also received me:terial .from the BLACK SEA, which 

presented the sam picture although tne keys (Schl11essel) 

were sor.JeWbat different. By cccparing both lots of 

mater:LB.l, after my return to BERLIN, it was possible to 

decypher it cCDplete:cy. Then, in BERLIN, when events 

were precipitated, I worked for some tlJile on Italian 

CJ'Phars, and occe.siona.lly on French and Spanish ones. 

Sa:ietlliles a whole country's r:nterial was left untouched. 

Then I resumed work on RUSSIA, wlu.ch was still umng a 

5 .. f:Lgure lmy, which was not a subtracter, however, but 

an adder. The break was successful. There were • 

dl.fficul ties, awing to the size pf the basic code book, 

which contained .501 000 gro\ips; it was hatted, end 

changed e.f'ter sOillt t i.Je. We discovered a f'Ol"lillla 

acpording to wh:Lch the qode grou; s were built up, a.Di 

identified thereby mmes of Bbips, equivalents of mmbers 

and pmctua.tian narks. The key (Schl.\lssel) changed <lail.1'.

We could only work on the systei;i when 80 to 100 nessages 

came in per day. The basic book changed ti.vice, but we 

always got into it again, although not nearly as far as 

with the English one. Wlu.le we were reading the 

4-figure systec 'vell, the 5-figure gave us very good 

results during the RUSSO-FilUSH war, although work was 

suspended. for e short tl.llle by ord.er. During this war 

the Russians introduced. a double recyphering system. 

Iater, we worked. together \~ith FINLAND. 'We had one 

break into the double recyphering adder systen, but it 

led to no pmctical results. We then lJ.ml. ted our 

attention to the 4-figure systen, which went well until 

'39. I r.i;yse1t wo.s head. of the Russian section, but l 

aJLiost all r.zy- personnel was taken away frar.1 rae; only a I 

few rerrined and coping m. th the tasks involved d.if'ficulti.es . 

of personnel, and betr".reen '39 and '40 I ho.d. to help with . 

eyphers of other countries. Owing to lack of staff I -

only remained in touch ~ith difficulty • . Autw:Jn 1940: what does tne cypher look like, nnd can we 

· break it at all, using large nUr.:Lbers of personnel" 

li.t all events ·we kept our head.a above water, but with 

some difficulty. At the beginru.ng of the war the question 

was whether we should. 1.1.0.nage to break it or not-. Plenty 

of •staff' was supplied. On 23/4 - I believe - at the t1.1ie 

" of the attack on JUGOSU..VIA, the systen cho.nged; previously 

1 a substitution system; 1 t bec.'.llD.6. an adder. ' 

wren the war with RUSSIA started, we could read a lngh 

percentage of it. The construction of the adder was 

\ peculiar, and consisted of repetitions. The suspicion 

arose that the adder must be based on a clear word-text. 

We received confiIT.llltion I'ror11 FINLAND t}u;t it was a book, 

obtainable cacmercially, in which each l~tter wns replaced 

by a figure ~nd these rows of' figures added to the codegrcups. The indicators only gave the page and ll.m of' the 

book. The indicator it self wo.s buried ( verborgen) in the 

text a.nd re cyphered by the add.J. tion of another nur.iber. We 

had th:l.s book in our dra\ver. One of our eqployees, living 

in the sane b.ouse as t:he nulitary attache, who had to leave 

suddenly and left a number of books bel:nnd, which were to be 

handed over to b9ok-sa.lvage, helped mn:self to the Russian 

books. We lea.med th::l title of the book, ~nd searched 

ever,ywhare until he ( (our erxployee)) re.i"'lefJ.bered that the 

book "IO.story of the COr..numst Pa.rty" We.Ls 0aL1ong them. We 

should have r.nnnged in any case, but the book facilitated.
