The case exposed deep tensions between the government and the military. The military was furious with Prime Minister Sheikh Hasina for negotiating with the mutineers instead of allowing the army to attack. In Bangladesh, a desperately poor South Asian nation with a history of catastrophe, army leaders have attempted to overthrow the government 21 times, twice successfully.
Dhaka's Metropolitan Sessions Court Judge Md Akhtaruzzaman announced the verdicts in a packed courtroom under tight security.
Besides the death sentences, 161 people were sentenced to life in prison; 256 people received prison terms between three and 10 years; and 277 people were acquitted.
Maj. Gen. Aziz Ahmed, director general of the Bangladesh Border Guards, said he was satisfied with the outcome.
"It was a huge massacre. We are glad that justice has been delivered," he said.
The defense vowed to appeal.
The death penalty is frequently carried out in Bangladesh for crimes like murder.
New York-based Human Rights Watch has criticized the legal proceedings and called for a new trial. The group said at least 47 suspects have died in custody while the suspects have had limited access to lawyers.
"Trying hundreds of people en masse in one giant courtroom, where the accused have little or no access to lawyers is an affront to international legal standards," said Brad Adams, Asia director at Human Rights Watch, in a statement on Oct. 29.
