Cryptic Question

Last week’s question was : -

The first was Wellington’s savior at Waterloo, the second linked Eva and Kylie, the third a heavenly wanderer, and the fourth was very handy with the mandible of equus asinus. What were they, and what was the fifth ?

Wellington’s savior was Prussian Marshal BLUCHER, whose timely arrival on the battlefield of Waterloo was one of the decisive moments of the battle. Little Eva and Kylie Minogue both had chart hits with the song , THE LOCOMOTION. The word PLANET is derived from a greek word that means wanderer. SAMSON slew 1000 Philistines with the jawbone of an ass. They were the first 4 locomotives built by George Stephenson. The fifth was the famous ROCKET.
So well done, Andrew !
