On the morning of May 28, 2020, U.S. Gen. Joseph L. Lengyel warned two of the Pentagon's highest-ranking officials that the situation in Minneapolis was about to get a lot worse.
Minneapolis police were expecting as many as 75,000 protesters to converge on the city that weekend in response to George Floyd's murder three days prior, Lengyel wrote in an email to Deputy Sec. of Defense David Nordquist and Chairman of the Joint Chiefs of Staff Mark Milley. The Minnesota National Guard had 200 military police officers standing by to assist, he wrote. "They are prepared to be armed should MPD and the Governor request it."
Only a fraction of the forecasted crowds showed up, but they were more than enough to overwhelm law enforcement defenses. That night, fires and heavy looting and vandalism claimed at least 20 buildings on E. Lake Street, including several restaurants, an AutoZone, Minnehaha Lake Wine & Spirits, a U.S. post office and a multi-story affordable housing project that was still under construction. Neighbors guarded their streets with baseball bats and garden hoses.
Police surrendered the Third Precinct around 10 p.m. The National Guard still hadn't been deployed to E. Lake Street at midnight, as the south Minneapolis police building erupted in an inferno that would burn it to a total loss — one of the most shocking images of an uprising that was spreading across the country.
"No joy," Milley wrote in an email as the police precinct fell. The general said he'd just met with President Donald Trump and Secretary of Defense Mark Esper. "Need you to call me ASAP," he told Lengyel.

The Pentagon emails — which the Star Tribune obtained recently in a Freedom of Information Act lawsuit — provide a new glimpse into the behind-the-scenes communiques leading up to the response to the unrest. Gov. Tim Walz would later lament the city's "abject failure" to get the riots under control. By the next morning, President Trump was threatening to send in the military as a show of strength.
"We were abandoned," an unnamed local government official told authors of a Wilder Research report commissioned by the state to assess what went wrong. "By the time the National Guard even came, most everything had quieted down."
Deployment by 'late afternoon'
In the months after the riots, Walz, Mayor Jacob Frey and other public safety officials deflected blame onto the others over questions on why it took so long to deploy the National Guard. The emails show the Guard was ready the morning of May 28 — more than 12 hours before the first Molotov cocktail shattered inside the precinct — and expected to be deployed by "late afternoon."
