To Israel's surprise, the Jordanian military intervened. The 48th Infantry Battalion of the Jordanian Army ran into the Israeli forces northwest of Samu; and two companies approaching from the northeast were intercepted by the Israelis, while a platoon of Jordanians armed with two 106 mm recoilless guns entered Samu. The Jordanian Air Force intervened as well and a Jordanian Hunter fighter was shot down in the action. In the ensuing battles, three Jordanian civilians and 16 soldiers were killed; 54 other soldiers and 96 civilians were wounded. The commander of the Israeli paratroop battalion, Colonel Yoav Shaham, was killed and 10 other Israeli soldiers were wounded.  
From 1939 to 1941, the Axis unquestionably had the upper hand in the conflict. During the first part of this period, nicknamed "the Phony War," hardly a shot was fired in western Europe. Only in the spring of 1940 did Hitler's forces resume action, conquering Denmark , Norway, the Low Countries , and France. The French, who relied on the defenses of the Maginot Line (designed to fight a World War I – style conflict of limited movement), surrendered after a nominal resistance effort. Most of the country fell under direct Nazi control, which a small portion to the southeast, with the town of Vichy as its capital, formed a pro-Axis government.
