Pan-American neutrality and Uruguayan politics trap Graf Spee

The battle itself was lawful, but the struggle in Montevideo became a contest over neutral-port access and political influence. Britain and the United States had already helped establish a Pan-American neutrality arrangement that denied German raiders useful regional ports and let the Royal Navy divert scarce convoy resources elsewhere. Graf Spee entered Uruguay rather than a potentially friendlier Argentine port, giving British minister Eugen Millington-Drake a strong local advantage. His connections across Uruguayan politics, journalism, and civic life combined with strong anti-fascist feeling to isolate the German ship. Local repair facilities were reluctant to help, and the damage commission saw only selected areas. Neutral law acquired force through diplomacy, local politics, and control of access.
