Passage: The Russo-Circassian War involved a series of battles and wars in Circassia, the northwestern part of the Caucasus, in the course of the Russian Empire's conquest of the Caucasus. Fighting lasted approximately 101 years, starting in the reign of Empress Catherine the Great and finishing in 1864. Although the Russian conquest of the Caucasus started at least as early as the Russo-Persian Wars, the term Caucasian War commonly refers only to the period 1817-1864. Those who use the term Russian-Circassian War take its starting date as 1763, when the Russians began establishing forts, including at Mozdok, to be used as springboards for conquest. The Caucasian War ended with the signing of loyalty oaths by Circassian leaders on 2 June1864. Afterwards, the Ottoman Empire offered to harbour the Circassians who did not wish to accept the rule of a Christian monarch, and many emigrated to Anatolia, the heart of the Ottoman territory and ended up in modern Turkey, Syria, Jordan, Israel, Iraq and Kosovo. Different smaller numbers ended up in neighbouring Persia. Various Russian, Caucasus, and Western historians agree on the figure of ca. 500,000 inhabitants of the highland Caucasus being deported by Russia in the 1860s. A large fraction of them died in transit from disease. Some of those that remained loyal to Russia were settled into the lowlands, the left-bank of the Kuban River.

Passage: The Packers started hot and never looked back, cruising to an easy win over the Eagles, who were tied for the best record in the NFL. The Packers took the ball and went 75 yards, with the big play being Aaron Rodgers hooking up with Jordy Nelson for 65 yards. However, two incomplete passes forced the Packers to settle for a 27-yard Mason Crosby field goal. After an Eagles punt, the Packers stormed 88 yards in 13 plays, taking 6:47 off the clock, ending with Rodgers connecting with DaVante Adams for a 6-yard touchdown pass. Rodgers continued to show that the Eagles' secondary was no match. The Eagles went three-and-out on their next drive, but this time Micah Hyde returned the punt 75 yards for a touchdown, extending the Packers lead to 17-0 in the first quarter. The Eagles finally managed points on their next drive, going 44 yards in 10 plays before Cody Parkey hit a 33-yard field goal with 13:08 remaining in the half. Unfortunately, for the Eagles, there was no stopping Aaron Rodgers. The Packers advanced 80 yards in only 6 plays, with Rodgers throwing for 60 yard on the drive, including the 27-yard touchdown pass to Jordy Nelson. The Eagles offense continued to sputter, punting on their next possession. The Packers continued their utter domination, moving to the Eagles 19 yard-line, but Malcolm Jenkins was flagged for pass interference in the end zone, moving the ball to the 1 yard-line. Eddie Lacy took it in on the very next play(the Packers two-point conversion attempt was unsuccessful) and the Packers led 30-3 with just 2:00 minutes left in the half. On their next drive, the Eagles managed to move 65 yards and Cody Parkey hit his second field goal of the half, trimming the score to 30-6 at halftime. The Eagles drove into Packer territory on their first possession of the second half, but Mark Sanchez lost a fumble that was recovered by Nick Perry. The Packers punted for the first time all night on their next drive, but the Eagles did nothing, punting themselves. The Packers proceeded to march 48 yards and Crosby was successful from 33 yards away, giving the Packers a 33-6 lead. On the following drive Mark Sanchez continued to give up the ball, with defensive end Julius Peppers returning an interception 52 yards for a touchdown making the score 39-6(Crosby's PAT was blocked). Sanchez drove the Eagles 80 yards, hitting Jordan Matthews 10 yards for a touchdown, closing the gap to 39-13. Rodgers responded by hitting Lacy 32 yards for a touchdown on a screen pass. Sanchez threw his second interception of the night on the next possession, but Crosby missed a field goal. Once again Sanchez turned it over (this time on a fumble), and Casey Hayward returned it 49 yards for a touchdown, making the score a humiliating, 53-13. Sanchez hit Jeremy Maclin for a 20-yard touchdown pass on the next Eagle possession, to close the scoring, giving the Packers a 53-20 victory. The Packers out gained the Eagles 475-429, but four turnovers (all by Sanchez) buried the Eagles.

Passage: After the failure of the coup in Kaunas, there were numerous small border incidents. On September 19, 1919, Polish troops attacked Gelvonai and encroached towards Ukmerge. On several occasions fights broke out regarding strategically important bridge over the Sventoji River near Vepriai. In October, when main Lithuanian forces were deployed against the Bermontians in northwestern Lithuania, the attacks intensified. Poles captured Salakas on October 5 and attacked Kapciamiestis on October 12. The front stabilized, but harassment of border guards and local villagers continued throughout late 1919 and early 1920. In March 1920, the Poles attacked along the railroad stations in Kalkuni and Turmantas. The situation was investigated by British and French observers and reported to the Entente. The situation somewhat improved only in late spring 1920 when most Polish troops were deployed in Ukraine during the Polish-Soviet War. At the time Lithuania faced a severe budget crisis - in 1919 its revenue was 72 million while expenses reached 190 million German marks. While the government was struggling to obtain financial assistance and loans, deep cuts affected the army. Instead of increasing its armed forces to 40,000 men, Lithuania was forced to cut them to about 25,000.
