Most damaging of all the private reports on the maneuvers was Voroshilov’s. At the banquet, in front of foreigners, he lauded the exercises. But while Tukhachevsky, acknowledging the shortcomings of tank performance in the rifle divisions, whose commanders still did not know how to use them to the fullest, deemed their efforts superior to what the Red Army had previously managed, Voroshilov internally denounced the tank formations and urged a doubling down on infantry.170 Part of his motivation appears to have been long-standing envy at the superior abilities and reputations of Tukhachevsky, Yakir, and Uborevičius (commander of the Ukrainian military district), all modernizers, and more knowledgeable about Germany.171
OPERATION X
On September 13, 1936, the city of San Sebastián fell to Spain’s putschists. The next day, Molotov, having just returned from holiday, followed up on Stalin’s telegram to Kaganovich the week before and chaired a meeting devoted to, among other matters, Spain. Attendees included Yagoda, Slutsky (NKVD foreign intelligence), Uritsky (military intelligence), Meyer Trilisser (Comintern intelligence), and Dimitrov, who recorded an agenda item as “organization of aid to the Spanish (via a smuggling scheme).”172 Later that day at Lubyanka, Yagoda presided over a meeting with Slutsky, Uritsky, Mikhail Frinovsky (head of NKVD border guards), and others to plan foreign military deliveries, including purchases abroad, for Spain. Before September 14 was out, Slutsky and Uritsky had presented Kaganovich with corrections to an operational plan, code-named Operation X.173
Also on September 14, the annual Nazi Nuremberg party rally concluded as Hitler announced further rearmament steps and unleashed his most rabid denunciation yet of the international Jewish conspiracy and the “infernal plague” of Bolshevism, which was “letting loose these wild beasts on the terrified and helpless world.” He mentioned German designs on Ukraine. In response to this drumbeat, the Soviet state publishing house issued a collection of translated original German documents from the period of the Great War,
Voroshilov sent detailed lists of all materials to be supplied in the Spanish operation to Stalin for approval.179 Because of the Non-Intervention Agreement, the Soviets had initially aimed to provide only third-party and “surplus” weapons, but, given the urgency, Operation X specified also providing Soviet weapons—just as the Spanish government had been requesting. Soviet intelligence was estimating that the Republic possessed one rifle for every three soldiers.180 On September 18, the first small-arms shipment, labeled CANNED MEAT, left a Soviet port. So did humanitarian cargo (flour, sugar, butter, canned goods, clothing, medicine).181 Secret Soviet documents stipulated that for the weapons “the customer should pay their full price.” Back on September 13, the Spanish Republic had secretly decided to evacuate the better part of the country’s gold reserves from Madrid by train. Spain had the world’s fourth-largest reserves, amounting to more than 2.3 trillion pesetas, or $783 million at prevailing exchange rates, a cache amassed by the crown over centuries: bullion bars, gold louis d’or, British sovereigns, rare Portuguese coins, Inca and Aztec treasure from the conquistador period. The crates began arriving at the port of Cartagena in the early hours of September 17, and for the next five and a half weeks remained in a hillside cave above the harbor. Prime Minister Largo Caballero had shipped the gold to the port at which Spain had agreed to receive Soviet cargo.
