How would you assess the original Australian assault on Tobruk?

Pretty much as Wikipedia:

Following the fall of Bardia, 7th Armoured Division with Australian 19th Brigade advanced to Tobruk which was isolated by the 7th Armoured Division on the 6 January. By 9 January it was surrounded.[34] After a twelve day period building up forces around Tobruk, O'Connor attacked on 21 January and Tobruk was captured 22 January, yielding over 25,000 prisoners along with 236 field and medium guns[6], 23 medium tanks and more than 200 other vehicles. The Australian losses were 49 dead and 306 wounded

A truly fierce siege against determined defenders which made a crushing amount of firepower an absolute necessity. Still kudos to the Aussies.

P.S: The article CBR posted shows just how terrible the intratheater supply situation of the Axis forces was. No fuel - no mobility, no ammunition - no firepower.
