Obi and a band of Jedis and Wookies come to aid the Clones.
In a blur Darth Maul charges the Jedis, taking out one and wounding everyone else (including two wounds on Obi-wan!).
Luckily a Clone Sniper (the last remaining Clone left in the base) fires a lucky shot into the combat which manages to momentarily divert Darth.
And allow Obi and the remaining Jedis to escape.
