George Mink and Five Passports for the GRU

By Constance Bell ·

A Soviet agent used five aliases to move spies through the world's ports for decades; the British kept the record of his movements in a file that identifies the holes in Western security.

In February 1935, a man carrying five different identities was hauled into a cell in Copenhagen, the capital of Denmark. He had been playing a high-stakes game of musical chairs with national identities, shifting between American, Polish, and Lithuanian personas to vanish into the fog of the Baltic ports. For the sailors and dockworkers who unwittingly shielded him, the cost was a compromised shoreline; for the West, the cost was a wide-open door for Soviet penetration.

The details of this operation survive today only as a series of archival catalogue descriptions, the original case files long since swallowed by time or silence. What remains is the skeletal trace of George Mink, an American and early member of the American Communist Party—the CPUSA, which sought to align domestic US policy with Soviet interests—who spent the interwar years as a ghost in the machinery of international transit.

The Copenhagen Trap

Mink’s arrest in Copenhagen was not a failure of his tradecraft, but a collision with the reality of borders. According to the record, he was found to be carrying multiple false passports, operating under aliases that spanned the map: Minkoff, Al Gottlieb, Abraham Wexler, Harry Kaplan, and Alfred Hertz. These were not merely names; they were keys. By assuming the identities of a Pole and a Lithuanian, Mink could navigate the fractured geopolitics of Eastern Europe and the Baltic without triggering the alarms that an American passport might have raised in certain circles.

Once the Danish authorities broke his cover, the Soviet response was immediate and surgical. The record establishes that upon his release, the Russians shipped him directly to Leningrad, the strategic Baltic port city that served as a hub for Soviet military intelligence. This was not a homecoming; it was a recovery operation. Soviet military intelligence, the GRU, which served as the foreign intelligence arm of the Soviet General Staff until the collapse of the USSR in 1991, could not afford to let a man with five passports and a map of their transit routes linger in a Danish interrogation room.

The Dockworkers' Pipeline

To understand how Mink moved, one must look at his movements in 1927. After visiting Russia, the record shows he became active in the international affairs of seamen's and dockworkers unions. This is the critical line. In the world of clandestine operations, the dock is the only place where a man can arrive and depart without a paper trail, provided he has the right friends in the union hall.

If the shape of this file is what it appears to be, Mink was not a traditional spy gathering secrets from embassies. Instead, the pattern suggests Mink functioned as a logistics officer for the 'Illegals' program, specializing in the physical transit and documentation of agents. He was the travel agent for the Soviet underworld, using union connections to secure berths and berths to secure aliases. The record’s mention of his subsequent presence in Spain—the European nation whose 1930s civil war served as a testing ground for Soviet influence—and Mexico, the North American republic that served as a frequent sanctuary for Soviet agents, confirms a trajectory of global mobility that few conventional assets could maintain.

The Soviet Network in the West

Mink was not an isolated actor; he was a gear in a larger machine of penetration that the British Security Service spent decades trying to map. The wider archival record shows a constellation of similar figures operating in the same orbit. Bianca Margaret Mynatt, a member of the German Communist Party and a secret courier with Moscow, entered London in 1934 (KV 2/3364). Susan Frances Benda, a technical journalist in the 1920s, was suspected of passing technical data to the GPU, the predecessor to the GRU (KV 2/1196). Kate Gussfeldt, another German Communist, used a falsely obtained British passport to enter the UK in 1927 to conduct espionage against the USA (KV 2/591).

Then there was David A. Petrovskiy, a Comintern representative in the UK during the late 1920s who operated under at least four aliases, including Max David and Marcus Goldfarb (KV 2/1396), and Rose Cohen, a journalist and Party member who became a regular visitor to the Soviet Union (KV 2/1396).

The connection is clear: the GRU and the Comintern were running a synchronized campaign of identity theft and institutional infiltration. While the couriers like Mynatt and the technical assets like Benda provided the content, they required a pipeline. The desk's reading is that Mink provided the plumbing. By securing the docks and the passports, Mink enabled a flow of agents across the Atlantic and through the Baltic that bypassed traditional customs and immigration screens.

The Krivitsky Reveal

The full extent of Mink's utility only became clear to the West in 1940, when Walter Germanovich Krivitsky defected. Krivitsky, a high-ranking Soviet spymaster who had revealed the plans for the Molotov-Ribbentrop pact, explicitly named Mink as a Russian agent.

The chronological gap here is telling. Mink was arrested in 1935, yet he only appears as a confirmed agent in the British record after Krivitsky’s defection. This suggests the file is a post-facto synthesis of intelligence provided by a defector rather than a record of active surveillance. The British were not watching Mink in real-time; they were using Krivitsky’s testimony to look back at the gaps in their own security and realize how a single man with a handful of fake passports had moved through their sphere of influence undetected.

The Desk's Reading

The record of George Mink is a record of a systemic vulnerability. The GRU did not just recruit spies; they built a shadow infrastructure of transport. The withheld portions of this record—the gaps where names of associates should be—almost certainly contain the identities of the maritime facilitators and union contacts who enabled these covert entries. The Soviet Union didn't just buy secrets; they bought the men who controlled the gangplanks.

The desk's reading is that the British kept this file not to track Mink, but to use his trajectory to map the GRU's global mobility patterns and identify 'safe' transit hubs. By tracing Mink from Copenhagen to Leningrad, and then to Spain and Mexico, they were identifying the nodes of a global network. A full release of the associated union files would likely show that the Soviet penetration of Western ports was far deeper than the official histories admit, relying on a caste of 'fixers' like Mink who treated national borders as mere suggestions. The pattern proves that the most dangerous man in the intelligence war is not the one who steals the plans, but the one who ensures the thief can get across the border.
