The captivities began in approximately 740 BC (or 733/2 BC according to other sources). And the God of Israel stirred up a spirit of Pul king of Assyria, and the spirit of Tigathpileser king of Assyria, and he carried them away, even the Reubenites, and the Gadites, and the half tribe of Manasseh, and brought them unto Halah, and Habor, and Hara, and to the river Gozan, unto this day. (Chronicles%205:26&verse=&src=! I Chronicles 5:26 ) In the days of Pekah king of Israel came Tiglathpileser king of Assyria, and took Ijon, and Abelbethmaachah, and Janoah, and Kedesh, and Hazor, and Gilead, and Galilee, all the land of Naphtali, and carried them captive to Assyria. (II Kings 15:29)
