The sentences were reduced under the penal code of the former Yugoslavia which the Bosnian judiciary must apply as of recently based on a judgement by the European Court of Human Rights.
The third indictee in the case, Musajb Kukavica, was given a four-year prison sentence pending appeal.
Dautovic was sentenced in trial court to 13 years' imprisonment and Gasal to six, while Kukavica was acquitted.
The convicts were involved in setting up a camp for detained Bugojno Croats and running it.
According to information of Croatian victims' associations, about 14,000 people passed through the detention camps run by the Army of Bosnia and Herzegovina, and the two largest ones were in Bugojno and Mostar.
As many as 300 Croatian civilians were detained in the camp set up at the Bugojno soccer camp. Thirteen inmates who were taken from the camp's premises to be questioned and exposed to torture are still unaccounted-for.
