Question: How far south of Dara was the location of Maurice's battle in 586? Passage 1:Maurice had to continue the war against the Persians. In 586 his troops defeated them at the Battle of Solachon south of Dara. In 588, a mutiny by unpaid Byzantine troops against their new commander, Priscus, seemed to offer the Sassanids a chance for a breakthrough, but the mutineers themselves repulsed the ensuing Persian offensive. Later in the year they secured a major victory before Martyropolis. The Sassanid commander, Maruzas, was killed, several of the Persian leaders were captured along with 3,000 other prisoners, and only a thousand men survived to reach refuge at Nisibis. The Byzantines secured much booty, including the Persian battle standards, and sent them, along with Maruzas' head, to Maurice in Constantinople. In 590 two Parthian brothers, Vistahm and Vinduyih, overthrew King Hormizd IV and made the latter's son, Prince Khosrau II, the new King. The former Persian commander-in-chief, Bahram Chobin, who had rebelled against Hormizd IV, claimed the throne for himself and defeated Khosrau. Khosrau and the two Parthians fled to the Byzantine court. Although the Senate unanimously advised against it, Maurice helped Khosrau regain his throne with an army of 35,000 men. In 591 the combined Byzantine-Persian army under generals John Mystacon and Narses defeated Bahram Chobin's forces near Ganzak at the Battle of Blarathon. The victory was decisive; Maurice finally brought the war to a successful conclusion with the re-accession of Khosrau.

 Passage 3:The Red Rovers, commonly referred to as the Alabama Red Rovers, was a filibuster force organized in Courtland, Alabama to support the Texas Revolution. Raised by doctor and planter Jack Shackelford in November 1835, the unit took its name from the red jeans of their uniforms and was outfitted with equipment from Alabama state arsenal. Consisting of some 70 men, nearly half the men in Courtland, the unit remained encamped until December 12 before setting out for Texas by way of New Orleans. After arriving at Lavaca Bay on January 19, 1836 and being accepted into Texas service on February 3, the Red Rovers were put under command of Colonel James W. Fannin.
