On 19 I?Tay 1950 Iloviniento T acional Revolucionaria elements and Commaunist
sympathizers took advantage of the disturbances accompanying the general
strike which began on 11, Thy to combine in a revolutionary attempt to over-
throw the Bolivian governont. The attempt was put down by the army and
police on the evening of the some day. Tho total number killed since the
violence began is believed to be 140, including approximately 25 troops, and
the injured 400, as opposed to the official government statement of 12 killed.
2. There was a pitched battle in the factory section of La Paz between the army
carabineros and 11172 and alleged Communist elements beginning early on 19 T-lay.
The army succeeded in defeating the rebels and gaining complete control of
the factory section on the evening of 19 !Tay. Approximately eighty persons
were killed, including a few troops.
3. At 7:30 p.m. on 19 T:ay the array took possession of the La Paz university where
Partido do la Izquierda Revolucionaria (PIR) leaders Ricardo i\naya, Jose Antonio
Arm and Carlos Ijendizabal had moved their headquarters. Jose Pereira was
arrested, but Ricardo Anaya, Jose Antonio Arzo, and Carlos Uondizabal were still
being sought by the police. Approximately three hundred students had been fur-
nished arms by Alfredo Suarez and organized by Pereira and Sergio Almaraz,
reportedly on orders from Anaya and Arzo. The students had smuggled numerous
areas left from the 1946 revolution into the university building for possible use
against the army.

regiments already in La Paz to maintain order. It was reported, but not con-
Y irnod, on 20 Nay that the Guachi regiment was suspected of having made plans
