<P> Once they receive the details of the test, Mainwaring convenes a parade to discuss their plan of action . Walker tells Mainwaring that he has made separate flags for both platoons to fly at the top of a tower, to mark the end of the test . Frazer foresees a snag: while they're performing the test, Godfrey will still be trying to climb out of the van, and suggests that he breaks his leg to avoid going on the test, but Jones suggests that they carry Godfrey the way the natives carried Dr. Livingstone in Africa . Mainwaring agrees . </P> <P> As the first part of the test, a race between the two platoon vans to the site of the initiative tests, gets underway, Jones suffers an attack of malaria and Frazer recommends quinine, but Godfrey only has tonic wine in his Red Cross bag . As they set off, they realise they have been travelling in a circle, and the Eastgate van is catching them up . Mainwaring tries to stall them by swerving all over the road, but Hodges stops them, allowing the Eastgate platoon to get ahead . However, their van breaks down and Mainwaring's platoon resume their lead . To stall the Eastgate platoon, Mainwaring decides to release some sheep onto the road, but they eventually end up blocking the Walmington - on - Sea platoon . </P> <P> They eventually come to a halt on a bridge, with the Eastgate platoon approaching from one direction and the Walmington platoon arriving from the other . Neither commander is willing to back down, so both platoons get out and push their respective vehicles . Hodges arrives and is accidentally pushed into the river by Wilson . Mainwaring and Square rush to help, but tell their respective Sergeants to let down the enemy's tyres, leaving them both stranded . </P> <P> After they arrive, the first initiative test begins, which involves puncturing balloons with bayonets . The Eastgate platoon take the early lead, mainly thanks to a drunken Corporal Jones! However, Walker and Godfrey use their initiative by using a cigarette and a safety pin respectively, and they quickly rush off . </P>
