WOMP and New York City. The most frequent location for escort exchanges was the Halifax Ocean Meeting Point (HOMP) off the WLEF home port of Halifax. The WLEF operated exclusively within range of anti-submarine patrol bombers; although weather often limited flight operations. U-boats were deployed cautiously in areas where air patrols were expected, so single U-boat encounters were more common than wolf pack engagements. The name was shortened to "Western Escort Force" (WEF) in the summer of 1943.
