Both types of operations continued, with Wellingtons and Hampdens increasingly joining in the leaflet raids and with Hampdens taking over the seaplane-base patrols. At least 1 of these 2 types of operations was flown on 37 out of 52 nights in this period but the number of aircraft dispatched was usually small.
A total of 228 leaflet sorties - 102 by Wellingtons, 64 by Hampdens and 62 by Whitleys - were dispatched between 17/18 February and 6/7 April. The only new feature was the inclusion of Poland in locations where leaflets were dropped, Poznan on 7/8 March and Warsaw on the 15/16th. One of the Whitleys returning from Warsaw - Flight Lieutenant Tomlin's aircraft of 77 Squadron - was running short of fuel and landed in a field as soon as he thought he had reached French territory. Members of the crew left the aircraft and asked the first person they met where they were. They soon realized they were in Germany and German soldiers were observed appearing. The crew managed to take off and were not fired upon until they were clearing the hedge of the field. They hedge-hopped safely over the Siegfried Line and landed in France. Only 6 of the leaflet-dropping planes were lost - 3 Wellingtons, 2 Whitleys and 1 Hampden. One of the Whitleys - again from 77 Squadron - was shot down by Dutch anti-aircraft fire while flying over Holland on 27/28 March; 1 crew member was killed and 4 interned. 7 more leaflet-operations planes crashed in England.
Anti-minelayer patrols were flown over German seaplane bases from 23/24 February until 8/9 April. The total number of sorties flown was 61 - 54 by Hampdens and 7 by Whitleys. No aircraft were shot down by the Germans but 4 Hampdens crashed in England.

Warships and troop-ships were known to be collecting in German ports and then sailing north for a possible invasion of Norway. Bomber Command aircraft patrolled the area every day; 45 Blenheim and 3 Hampden sorties were flown. Coastal Command aircraft were also involved in the search. 21 Blenheims found ships on 3 different days and bombed them but without obtaining any hits; the German battleships Scharnhorst and Gneisenau were among the targets. No aircraft were lost during these operations.
