[Q]: Question: Did the operation that Musicki contacted the Chetnik leader about actually take place? Passage:Musicki was stationed in Slavonski Brod at the time of the Axis invasion of Yugoslavia in April 1941 and served as the Royal Yugoslav Army commander responsible for the railroad between Belgrade and Zagreb in the rank of colonel. He demonstrated his support for the Germans by helping their forces during the invasion. Yugoslavia was quickly conquered by the Axis powers and Musicki remained in Slavonski Brod for several months after the conquest. He attempted to join the Ustase Militia there, but was rejected. He went to Belgrade in mid-August, where he was received by Zbor leader Dimitrije Ljotic. On 6 October, Milan Nedic, the Prime Minister of the Axis-installed puppet Government of National Salvation, appointed Musicki to lead the Serbian Volunteer Command (, SDK). Musicki was involved in executing Serb civilians in the town of Cacak in December 1941. He and Milan Acimovic contacted Chetnik leader Draza Mihailovic on 5 December, possibly in an effort to warn him in advance of the assault the Germans had planned, codenamed Operation Mihailovic. This action prompted the Germans to question Musicki's loyalty. He was removed from command at the end of 1941 and imprisoned by the Germans, but was later freed at Nedic's intervention.

[Q]: Question: On what date did Recitation win its maiden race at Newbury Racecourse? Passage:After finishing third over five furlongs on his racecourse debut, Recitation won a maiden race over the same distance at Newbury Racecourse, beating I'll See You by half a length. The colt was then moved up sharply in class for the Group Three Coventry Stakes over six furlongs at Royal Ascot in June in which he was ridden by Greville Starkey and started at odds of 11/1. In a performance which Timeform described as "a revelation", Recitation took the lead a quarter mile from the finish and drew clear of the field to win easily by five lengths from Motavato, Bel Bolide and Another Realm. The form of the race was subsequently boosted when the third and fourth placed horses won the Gimcrack Stakes and the Richmond Stakes respectively. In the July Stakes at Newmarket Racecourse Recitation started 2/5 favourite against two opponents, but was beaten two and a half lengths by Age Quod Agis.

His mother was a daughter of John Moyle. After education at Liskeard grammar school and Bodmin grammar school, he went to Westminster School under Richard Busby, recommended by his uncle William Morice.

In January 1674, Prideaux recorded in his letters a visit to his home of William Levett; with Levett came Lord Cornbury, son of the Earl of Clarendon, Levett's principal patron. In other letters, Prideaux mentioned alliances with Levett in ongoing church political maneuverings. At the university he was known for scholarship; John Fell employed him in 1672 on an edition of Florus. He also worked on Edmund Chilmead's edition of the chronicle of John Malalas.
