Today I visited one the places where the secret agreements between the Spanish and american representatives took place in February 1777.
It's in the north of Spain in a city called Vitoria.

Spain was weak at the moment, after the seven years war they had sustained serious losses against the British, so couldn't face great Britain openly.
The spanish representatives were Grimaldi, Gordoqui and the american representative Arthur Lee.
The american colonies received from the spanish treasury 70.000 pesos first and later another 50.000.
Goods valued in 946.906 reales and 215 bronze canons, 30.000 muskets, 30.000 bayonets, 512314 bullets, 300.000 pounds of powder, 12868 grenades, 30.000 uniforms and 4000 tents.
Thanks to that help, the american colonies achieved a great victory at Saratoga battle (Oct. 1777), which finally moved the french to join the american side, in 1778.
Later the spanish, 1779, joined the americans in open war, fighting in the South, Gulf coast and Midwest with total success.
