Operation Red Sheepskin: Greece's Stay-Behind Network and Civil War Allegations

SUMMARY

This dossier investigates the claims surrounding "Red Sheepskin" (Κόκκινη Προβιά), alleged to be Greece's secret "stay-behind" organization during the Cold War. Stay-behind operations involved placing secret operatives within a country to form resistance in case of enemy occupation (Source: [1]). While Operation Gladio refers specifically to the Italian branch of these NATO/CIA-backed networks (Source: [3], [12]), similar organizations are documented to have existed across Western Europe (Source: [8]). Allegations suggest the Greek network, established after the country's civil war, operated under an explicitly anticommunist mandate (Source: [4]) and extended its influence into domestic politics and electoral processes (Source: [6]). The U.S. Central Intelligence Agency (CIA) is alleged to have become heavily embedded in Greece after the Civil War (Source: [14]).

STRONGEST CASE FOR

The strongest argument for the existence and influence of "Red Sheepskin" is its alignment with the broader, now largely acknowledged, NATO/CIA "stay-behind" strategy across Western Europe, as confirmed by parliamentary inquiries and declassified documents related to Operation Gladio (Source: [3], [8]). Given Greece's intense post-WWII civil war and its strategic geopolitical position bordering communist states (Source: [4]), it would have been a prime candidate for such a clandestine anticommunist network. The direct allegation that the network intervened in Greece's political processes, while serious, reflects concerns raised in other countries where Gladio networks were accused of exceeding their defensive mandate (Source: [7]).

STRONGEST CASE AGAINST

The primary counter-argument against specific allegations concerning "Red Sheepskin's" domestic political interference is the lack of direct, verified primary documentation from official Greek or Allied sources detailing such activities. While the existence of a Greek stay-behind network is plausible given the Cold War context, and the U.S. had significant influence in post-civil war Greece (Source: [14]), specific claims of electoral manipulation (Source: [6]) remain single-source assertions from less authoritative outlets. Without declassified government documents or corroborated testimonies, these particular claims are difficult to substantiate beyond the general understanding of Cold War-era covert operations.
