The Ambassador in Argentina (Weddell) to the Acting Secretary of State
[Received 5:33 p.m.]
13. From a reliable source I learned last night that attitude of the Argentine Government has changed during the last few days and that it is now disposed to bring pressure to bear on Paraguay which apparently cannot continue fighting without Argentine support financially and by munitions and transport. Thus Argentina holds key to situation. Argentina will probably try to induce both parties to agree to 6 months’ armistice. Uruguay now apparently reconciled to transfer of negotiations to Buenos Aires.
Repeated to Asunción, La Paz and Secretary of State at Lima.
