Biography
Monserrate Sanchez of Río Piedras, Puerto Rico, was sentenced to four years in prison under the Espionage Act. The sentence was commuted to two years. He served at Atlanta Penitentiary from July 25, 1918, through April 15, 1920.
The Puerto Rico row records four years, commuted April 22, 1919 to two years; actual departure at expiration is separately dated April 15, 1920. The table separately identifies sentencing, nominal judgment and circumstances of execution; no new jail admission or actual-service counter is inferred.

The presidential-clemency table in the 1921 Senate amnesty hearings records a sentence imposed July 25, 1918: Four years at Atlanta. Commuted April 22, 1919 to two years. A pardon, commutation, nominal expiration or parole eligibility is not itself evidence of the day of physical release; the imposed or reduced term is not a measured time served.
